Problem creating Cura profile

[Patronus 3]

I may misunderstand how profiles work in the latest release of Cura, please help. I am trying to create a new profile but every time I select "Update profile with current setting" my changes are undone and it seems to revert to some sort of default. I actually lost many hours of printing and filament today because I assumed my profile changes are saved and then I started printing, only to find out after some time that my changes have indeed not been made and the profile has not been updated. So I thought maybe I misunderstand things and I should create a new profile if I want to save my latest settings. But when I select "Create profile from current settings" my changes are also undone. For instance I want to turn retraction off in my new profile. But when I update the profile or create a new one, retraction is on again and all the other settings I have made are lost, and it reverts back to some previous profile. It even now randomly changes things like layer height and I haven't even touched that. And I can't change the XY distance under support. It jumps back to 0.2 no matter what I type in. As if some hard coded profile now exists and I cant change it.

I'm using Cura 3.3.1 I have restarted Cura. I've restarted my computer. I've deleted profiles and tried creating new ones. It looks like this starts happening every time I switch retraction off. From that moment onward Cura has a mind of its own. What's going on?
