Form Addresses Changing

I've had a few form addresses change after I produce a QR and get my marketing material squared away. Why would this happen? I don't have a screenshot as I already changed it on my site, but is there any reason that this would happen??

Hi Jeff,

Thanks for reaching out to Jotform Support. Can you explain a bit more about the issue, so I can get a better idea of what's happening? Also, If you can share the link to your form and the website, I can check it out and help you with a solution.

After we hear back from you, we’ll have a better idea of what’s going on and how to help.

I unfortunately already fixed the issue as I panicked about how many leads I was possibly losing. Next time it happens, I'll leave it up and report it.
