Open the attached file in Calc 5.3.?.? then delete any cell in column A with your keyboard delete key. You’ll notice that the adjacent cell in Column B on the same row is also deleted. Vice versa works as well (delete B, A is deleted - only for the rows that have cell’s filled in Column A and B.
I do not know why this is happening, but it only started on 188.8.131.52. I am running 184.108.40.206 on a 64bit Linux and it’s fine. No issue with this exact same file. I can’t seem to reproduce it on a new spreadsheet as well in 220.127.116.11. Thoughts?
