Since I updated to 24.8.2.1 I have experienced Calc adding extra closing brackets. It doesn’t happen all the time, but when it does it does a “Hotel California”; once you’re in, you cannot get out. I often have to reenter the formula via the wizard for it to be accepted.
This is a recent example. My formula is
=IF(B$8="","Straddle value + buffer")
This is what I see in Calc
=IF(B$8="","Straddle value + buffer"))
It doesn’t matter what I do to remove the extra bracket, it keeps comes back. In the cell it gives an ERR:501. In this case, if I view it in the wizard I see
"Straddle value = buffer")) )
If I remove the extraneous brackets using the wizard, they are inserted when I close the wizard.
