Because there are two issues here I will answer the first having t do with the word icon which began the thread. I will use your information to address the attachment later which became part of the thread trying to show the issue graphically..
My Word account is correct.
I saw that the icon is so odd and different from all others it really does not blend in so figured there was something wrong.
All icons seem to have the same basic scheme in color and shape but this is way off.
Apparently, after finally seeing another like it in Office 2016, there is no problem in my 2019 Home and Student.
The oddity has been confirmed by 2 other users with Word, saying there was a problem with Windows development.
I know nothing about why it is like this, I am glad although it is odd looking, it is normal for Windows + functional.
I will continue to see if I can post a picture but only to see if it can be done on my end.
I swear I upload to forums all the time with no issue. I also swear I did exactly as you say in the uploading process. I wonder if my upload cache coud be full? I have always had that problem here but not elsewhere.
