--- Comment #3 from software.v9...@slmail.me --- There is a cell protection. If you highlight all cells and try to remove the cell protection, it doesn't work. I guess this is because there is a matrix formula in it and it may be automatically protected? The sheet protection was my misunderstanding: if the check box "protect this sheet and the contents of the protected cells" is checked, then I thought it is already protected. So I tried to uncheck it to unprotect. Wrong logic. -- You are receiving this mail because: You are the assignee for the bug.
