VoIP Innovations module metered trunk gives whoops

I set up the VoIP Innovations module using their provided key, which automatically created trunks for me. However, I’m facing an issue: when I try to edit these auto-generated trunks under PJSIP, I get an error message. Interestingly, if I create a trunk manually for any provider, I can edit it without any problems.

Has anyone else experienced this, or is there a workaround for editing these auto-generated VoIP Innovations trunks?
