Render Scale over 100 not save

Just to note I followed my own advice and my MSFS is still not saving as I have installed it on a separate drive I appear to have two locations for my user.cfg files one on the E drive where MSFS is installed and one on the C drive. I have tried deleting both and letting it set it up again but still won’t work.

C:\Users\benrb\AppData\Local\Packages\Microsoft.FlightSimulator_8wek???bbwe\LocalCache

E:\WpSystem\S-1-5-21-???%£-142???08-2235???235-1001\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe

Does anyone else have any ideas, it keeps resetting to 100% after MSFS is closed.
