invisible font issue after compile

My export & import aren’t holding on to my choices

I tell it to import as .DOCX in both cases but as soon as I close the box and reopen it’s defaulted to .DOC
After compiling its does a second step --CONVERTING FILE
When I open the file in Word 2007 even though it says its a DOCX file, Word opens it in compatibility mode

I noticed that if I added a new paragraph in Word, it went into COURIER NEW, so I showed invisibles and at the end of every single paragraph I saw COURIER NEW invisible instead of CALIBRI invisible

this is a new problem after having to unstall1.96 and reinstalling 1.90. I had saved my preferences , and restored them after the reinstalling but nothing changed

HELP :question: :question:

Hello, anyone there?
