Some of my drawing files behave strange.

Every time that I open the file my drawing NOTES seems to have duplictions inside:

Something like this:

38x19 RECT Tube:RECT Tube:RECT Tube:RECT Tube:RECT Tube:

I can delete the duplications, but next time its back again and keeps duplicating every time I open the file.

Find and Replace does not pick up this duplication.
