Olive drab dim re-appears after pdm release

Hello;

      I have a situation, where I'll have a dim, work through a project, in this case, do several check ins, & not see an old olive drab dim. Then release the file in the pdm pro, & then open the drawing and the dim appears. Again didn't see it all the time I was working on it.

     Just wondering if anyone has chased a similar issue down, & found out what's going on.

Thanks in advance for any input;
