Another strange thing I noticed:
I have only one form activated. However after submitting a form in frontend, I get a second form activated:

I don’t have such a form at all. I deactive it and it disappears!

However when I fill in this form in frontend

I get a new actived form again with this name!
Very strange. Something is wrong here…
