Settings: Excel won't complete closing parenthesis anymore

[RPJVi]

Hello,

I think I accidentally changed an Excel setting.
When I enter an incomplete formula (i.e. final parenthesis missing), it doesnt auto-complete anymore and jump to the next line, instead it gives a blinking highlight and stays in the same cell.

Hopefully someone can help me, I use it a lot
Thank you in advance!
