Installed an update to SoftMaker Office 2018 on my Catalina MacBook Pro & Mojave iMac. All was OK on the iMac but the other was an abortion, settings wouldn't stay set, default document format kept returning to what I would never use & the user info template would not be saved.
Used an app called Find Any File to track down & delete any remnants of SoftMaker other than emails. Reinstalled the new version and everything now behaves as it should.
