Dynamic, Annotative block, parts not scaling as XREF for some

[tedg]

We have a dynamic room-tag block, which is annotative, and it works great in the same drawing.
But when xreffed, the top line (which is a multi-line attribute) does not scale properly.

Note, this doesn't happen for everyone, some users they behave fine as expected.
I'm hoping this is some variable or setting that I (and other users) have that we can switch.

If anyone has a solution or ideas on things to check, I'd appreciate it.
(I searched the Forums and didn't see a similar problem brought up that I could find)
Thanks
