Behavior when creating multiple different mail forms with ContactForm7

I’m using Zoho CRM Lead Magnet version 1.7.8.6. I’ve created multiple mail forms with different IDs using ContactForm7. (In this case, I created two mail forms.) One of the mail forms was set up to integrate with the Zoho CRM Lead Magnet plugin, while the other was not configured for integration.

For the mail form with integration settings, the submission process completed successfully. However, for the mail form without integration settings, clicking the submit button did not complete the submission process.

Is the above behavior expected with the Zoho CRM Lead Magnet plugin? If possible, I hope that an update will enable the submission process for forms not integrated as well.
