Saved form still prompts for me to save page again

Hi there! Despite having saved changes to my form, the following dialogue box still populates every time I try to navigate away from my saved form:

“This page is asking you to confirm that you want to leave – data you have entered may not be saved.”

I believe this is interfering with the Contact Form 7 Paypal plugin I’ve installed which will not save the changes I make to configure the PayPal integration.
The issue presents across various browsers.
