I am having an issue that is driving me nuts and wasting my time.  I'm sure there is a simple answer but I cannot find it.

I have set of notes that I have made into a block in drawing A named it  X (part-info)

I bring it into drawing B, edit it, save it with a new name Y (x1472).

I open drawing C, bring in block Y but I get X!!!

this is what the block tree looks like

How do I get block Y to take on changes?  They are all in correct folder.

thanks,

B
