Lost almost all of my OmniFocus preferences on mac

I switched my mac profile from standard to administrator and for some reason all of my preferences in OmniFocus got deleted. It’s like starting with a brand new OmniFocus. The welcome screen showed again.

I still seem to have all my tasks, projects, and anything that syncs with Omni servers. But I’m missing any changes I made in Preferences on the OmniFocus mac app. I also lost all of the custom keyboard shortcuts that I made for OmniFocus in macOS System Preferences.

Does anybody know where I can find and reinstall my old preferences, and why these preferences got lost?
