Removed Stripe Add-On – Submission still trying to collect payment

Recently re-developed this site and removed payment processing, including the Stripe add-on and any calculations that the ‘Corporate Services’ forms were doing. For some reason, when I try to submit them, I get an error that looks like is telling me the plugin is still trying to collect payment. Please see this screenshot for the full error:

The form is still saved in the backend, but not emailed to my client – and their customers don’t know that because it shows “Server has encountered an error.” It’s a mess!

Thanks for help ahead of time!
