Readability Stats Missing

[blyounker@gmail.com]

Hi, suddenly my grammar and spell check aren't checking anything, and my readability statistics show 0 in everything. In addition, the words on the readability pop up started appearing in French! I've gone into the Properties>Authoring and Proofing Tools>Spelling and Grammar and verified that the only box NOT selected is to select from Main Dictionary only. Under the section for Grammar, the Writing Style is "Grammaire" and when I click the drop down, that is the only selection. I have a Mac running iOS 12.7.4, and my Word is 2019 v 16.78.3. There is no one else that uses my system, so it isn't anyone else getting in and changing it. Additionally, this happened last week, and I ran Disk Utility which seemed to clear it up after a Word restart. This time after the restart the Writing Style converted back to "Grammar" for as long as it took me to try to run the spell check again and see the readability stats show 0. (i.e. when I went back into the properties it had reverted to "Grammaire".
I don't know what the heck is happening or what else to do.
