Hey There Andy, I seem to have found a bug or atleast I think. I cannot see the text on the Upload a sync, so I can't see the code.
I already tried to fix it from Google's instructions such as contrasting after a screenshot, it still didn't work.
"It's an error that happens due to the UI update and it has been fixed on future builds."
It's likely the same bug mentioned; it probably occurs because the text is blank and the UI has also been updated. It will most likely be fixed in future updates.
