Irrelevant error message returned on an attempted bug report update

Device: PC
Browser: Opera
OS: Windows 10 Home

Steps to reproduce:

After entering a bug report click the "Edit" button. On the loaded for editing page make some text edits to the previously submitted report. Click Submit button. Two errors show in reddish color above the reported error Subject box saying:

You have to enter a poll title.
You must enter at least two poll options.

I just tried to make an update to a previously submitted report text for better clarity, so I'm perplexed on the "poll" mentioned in the errors.

Anything else to add:

Works fine for mod, but might be just because I am mod

Same error for me

I submitted a bug report on this matter and later I found this post about the exact same problem.

The problem now is that I can't edit it, just delete it.
