Autocad Selected Xref Block Is Not Editable

I have a drawing of a siteplan where I have attached my title block as an xref. For every drawing there is an individual project numer, project title etc and this is what I'd like to edit. I have the basic text set up in the title block with the righ font and size and just need to change a few numbers. From within the current drawing, select the reference that you would like to edit. If the object you select in the reference belongs to any nested references, all the references available for selection are displayed in the Reference Edit dialog box. In the Reference Edit dialog box, select the specific reference that you want to edit.

Some times when i'm trying to edit a block i have the following message:
'Cannot save back changes because objects in the working set refrence objects outside of the workset. the refedit session is etill active. please press F2 after dismissing the dialogue to see the list of missing refrences'
and after hitting F2 i always have these 2 lines whatever the file i'm workimg on :
' **Application refrences to other objects:-
** Application refrence missing:
AcDbBlock RefETag. to AcDbBlock Refrence.
Regenerating model
**Undefined Shape124
**Undefined block #-1 '
Notice : i dono if it has somthing to do with this, but i notice that this dialogue appears usualy when i'm trying to add a new object to my block .

Edits an xref or a block definition directly within the current drawing.

Accepts the currently highlighted reference for in-place reference editing.

If you are editing a block reference with attributes, you can enter y to display the attribute definitions and make them available for editing. The attributes are made invisible, and the attribute definitions are available for editing along with the selected reference geometry. When changes are saved back to the block reference, the attributes of the original reference remain unchanged. The new or altered attribute definitions affect only subsequent insertions of the block; the attributes in existing block instances are not affected.

All

Objects in the selected reference will be automatically included in the reference editing session.

Nested

After you close the Reference Edit dialog box and enter the reference edit state, you are prompted to select the specific objects in the reference that you want to edit.

Advances through the reference and nested references available for selection. The currently selected reference is highlighted.

Autocad Xrefs How To Use

A working set is formed with the objects you have selected for editing. The working set includes objects that can be saved back to update the xref or block definition. When you save back changes, changes made to the objects in the reference file are saved without actually opening the reference drawing or recreating the block. The working set is visually distinct from the rest of the current drawing: all objects in the current drawing, except objects in the working set, appear faded. The XFADECTL system variable controls the fading of objects while you edit a reference in place.

You can select objects in xrefs for editing even if they are on a locked layer in the reference file. When a reference object is part of the working set, you can unlock the object's layer and make changes to the object. Only the changes made to the object are saved back to the reference file; the xref layer remains locked in the reference file.
