Can’t edit the text in the sub label under the signature

I am using a friend’s form as a template and it has let me edit and save changes to everything except the sub label under the signature.

it says it’s saved but reverts back to her text every time

please help

edited - finally managed it but could only do it via the web interface in the settings for the signature box . It wouldn’t work editing the text directly or via the settings tab using the app 

I have cloned your form to my account and checked the Signature widget using JotForm mobile app. I was able to edit the sub label of the signature widget from the field properties without any issue.

Please check again and get back to us if you need any further help in this regard. We will be happy to take a look again.
