Modified text in a block moves next time file opened

Hey all! I have .dwg files originally created in ACAD. When I open the file in DS everything is fine. I make changes to text in a block, I save and close. But if I reopen the same file, any text inside a block that I edited last time will be shifted down and to the left slightly, about .125-.50inches (3-12mm). The rest of the text in the same block not edited stays where it should. No other parts of the drawing behave this way, just text in a block that was modified.

Any idea why this happens or possible solutions? Thanks in advance for any insight/time.
