look in model space, at elevations in top red rectangle, you will see when focused in, dimensions go vertically up past the top of the ceiling at the top of each elevation. This happens everywhere thru out the drawing in elevations, not just vertical dimensions but the horizontal as well. Just focus in on any elevation, it is always the same dimensions that do this over and over after I open up the file. Take any dimension that looks corrupted , click on it, go to properties and then click ok and then look at the same dimension and you will notice it gets corrected. This is a big problem either when I have to work on the file or print it, you can waste almost an hour to re set everything.
