If this does not solve this issue, does it happen to only this drawing or all drawing?
If only this drawing, could you check the standard used in this dwg from Options> AM:Standards. I suspect yours might be blank or wrong.
If all the drawing, could reset settings to default to repair the software, then check issue solved.
Could you send me the drawing with issue? Let us check what issue it has.
The workaround for this issue is to copy and paste all drawing into a new file.
