Form submission fails with Wordfence Activated

Yesterday I had issues with submitting events and the plugin had a security issue which was reported by Wordfence.
https://www.wordfence.com/threat-intel/vulnerabilities/detail/modern-events-calendar-7110-authenticated-subscriber-arbitrary-file-upload
Since then I’ve uploaded the latest Ver 7.12.0 which should be fixed.
Wordfence is not reporting any issues with this plugin now.

BUT…I still can not submit a new event from the frontend when logged in as a Subscriber.
If I deactivate Wordfence then the submission works.

The only way submitting an event on the front end works with Wordfence activated is to change the user role to Admin.

Is there something I can do get this to work with Wordfence activated?

Thanks
