Comments are Garbled

The comments for each submissions in the Android app are unreadable because they are made up of a bunch of joined letters. As if encrypted. 

On the web app through the PC they are readable when opened individually, but garbled when exporting to Excel or PDF. 

I have a key.

That means that those data was encrypted. To decrypt the data, please follow this guide https://www.jotform.com/help/344-Encrypted-Forms-and-How-to-Use-Them.
