Email inbox identical in Thunderbird

I have 4 email accounts with Thunderbird...3 AOL and 1 Gmail. This morning upon checking me emails, I've noticed that all 4 inbox's are identical. I thought I was hallucinating. ..how did this happen? Is it some Hacker? I did a little research in Google and read Only that there are people who prefer such a layout, but I am not one of them. I couldn't find one response on how to get this undone, if that is possible. This is only Win 7, not Win 10....but I prefer Win 7 TB layout better.

All the emails from all 4 accounts are getting duplicated in each of your T-Bird folders?
Did it work right before?
Did T-Bird update?
Have you researched the T-Bird Help area? I know it sucks.

first delete email from Thunderbird and again add the email on TB it will work.

Thanks
