TextEdit keeps changing font size from 12 to 14 when I click back into the window
My TextEdit keeps changing font size from 12 to 14 on its own. Default is 12 (I know how to change and check this--it's set at 12 pts) but sometimes when I go to another window (Firefox or Chrome, for example) when I click back the font size changes to 14. It's really annoying since I'm using TextEdit to take notes during Zoom calls. I have to keep 6, sometimes 7, applications running at the same time for work and MS Word (as the 7th or 8th app open) slows things down too much, so I need TextEdit to run properly. I'm on a mid-2012 MacBook Pro 13" using Catalina 10.15.7.
