I have seen related questions to this but no solutions.
In the last few days, MS word (MacOS High Sierra Word v. 15.37) has been randomly changing font. I have my default font set to Times New Roman 12pt but it changes to Helvetica 12pt randomly, sometimes mid-sentence, sometimes mid-word. Sometimes copying TNR 12pt into a new document and choosing "source" formatting results in a document with mixed (mid-sentence) fonts all through the document. When I select all text and try to change back to TNR, the text does not change (and the font box remains blank). If I try to clear formatting (not ideal when writing a reference list in APA format) and then go to write stuff in, it again changes to Helvetica randomly. I've tried multiple times to go in and set the default font back to TNR but it doesn't work.
Edit: Just tried to manually change the font of individual words to TNR. I can't do it, its locked to H. somehow. Hitting 'clear formatting' does nothing.
The only thing I've done differently in the last few days has been upgrade to High Sierra. Around the same time, I also opened and modified a document someone else sent me which was written in Helvetica, and this was when I noticed Helvetica had somehow hijacked my system.
Please help. I am submitting these documents for publication and its frustrating in the extreme.
