Jotform link appears in excel file when exporting submissions.

When exporting our submissions to an excel sheet, each entry has www.jotform.com in each cell with text. Is there a way to turn this feature off?

It just showed up this afternoon

I have tried the export feature and selected excel as the format, but I'm unable to reproduce it. Can you please share the form URL in question so we can take a look? Also, can you please provide us a sample screenshot?

Lastly, please confirm if the jotform link that was inserted only appears in new submissions or it appears in all submissions in your excel file?

Looking forward for your response.
