Data missing after submitting forms

There are forms submitted but there is no data while this message appeared in one of the columns
error on line 20 at column 44: Char 0x0 out of allowed range

Can you please explain this to me? and what I can do to retrieve the initially entered data?

@Reema, could you also share a screenshot of the same? The screenshot should help troubleshoot your issue.

Hi… I cant see my forms Submitted.
I can see in my phone “enviado” but the form cannot be seen in the kobotoolbox (web)
