Description text disappears from revision block when drawing is saved to WPDM

Greetings,

I've had this re-occuring problem with drawing files. After I have completed a drawing and go to save it into our workgroup PDM vault the revision block description text disappears. This annoying problem has happened numerous times. Then I re-take ownership of the drawing, re-type the description text, and bump the rev level (exp: B+) when re-entering the files back into WPDM, then its OK. Does anyone have any ideas how to solve this issue?

SW2012 SP5.0

Thanks,

Larry Z
