Why read submissions suddenly shfited to unread?

I have many forms and I chak whether or not I have new submissions several times a day. I logged today in the morning and there here no submissions and in 3 hours I logeed in I see several forms had 3, 2, 1 and 64 unread submissions. I have checked and these are not resent submissions plus I dont get that many in just 1 day. What is the problem? Thank you

Unfortunately we had a bug on the submissions counter that made it display a different number from the real one.

Thats ok, thank you for your prompt response.

You are very welcome.  If any of your forms currently show an incorrect count, let us know which ones and we can manually reset the counter.

I moved your last question to a new thread as it is a different question. You can see it here:
