Hi!
I just have the same issue today... However, I just noticed that there was this [Group] just after the file name (on top of the file that shows the file name that you are working at) and it means that you selected more than 1 tab on that worksheet. Not sure how did it happen (maybe by accident) and it was saved just liked that without me noticing it. Not sure if it is the same issue with you but you might want to check if that is the case and just ungroup those tabs
Hope this helps... Stay safe everyone... :)
