I have a Calc file in LibreOffice 5.2.1.2 on Windows 10 Home 64 bit.
When I add or remove lines, the drawn objects (like a triangle or crescent) change size and location. Here is the file: Genetics file (see rows 32 to 60 - the large triangle has become large and move if rows are added above it.)
This also occurs when I save the file and exit then re-open the file.
Any suggestion?
