Excel 365> autofill, flash fill, custom lists not working
Hello.
Working here on a latest Windows 10 Pro with latest Office 365 Version 2212 Build 16.0.15928.20196 64-bit.
I had found a couple of months ago some weird behavior and today was trying to resolve it as it got too annoying to live with.
Issue 1. When I try to enter Options->Advanced->Edit Custom Lists, nothing happens. The "Advanced Options" window closes for a moment and opens again. So, there is no way to edit custom lists.
Issue 2. But what is most frustrating is that Excel does not understand simple series any more. I enter 1 and 2, select them both and try to stretch with autofill function, but just receive an endless line or columnt of 1s and 2s. So this:
Becomes this:
Same goes for Monday and Tuesday, for example. When I enter dates, say 1.01.2023 and 1.02.2023, I get a sequence of them in turns.
If I try to Ctrl+E them (Flash Fill), I get this:
I tried reinstalling Office. Uninstall / Clean Registry / Clean using Microsoft SARA, and then installing again after restarting the computer - no luck. I get the installer from my Microsoft account page.
The needed "enable fill handle" and all the other options have been turned off and on again a gazillion times - nothing:
Anyone had the same problem with lucky ending? Or am I the only "lucky" here?
Thanks in advance
