Full Event showing a ‘Cancelled’ message on booking button

#_BOOKINGBUTTON is showing the text for an event being cancelled when the event is actually just full up.

I can change the ‘event cancelled’ wording in the booking button feedback messages section in the admin, and this change is shown on the site. I have not enabled the event status option, so am surprised to even see the option for setting the cancellation wording. Subsequently, I did enable the ‘status’ option to verify the event does have the status ‘active’ not ‘cancelled’. I have now disabled ‘status’ again, but I still see the options in the booking button options.

I’m concerned Events Manager somehow thinks this event is cancelled and may implement other logic as well somewhere. What are the implications of ‘cancelled’? It’s important the event stays live as it’s part of an online conference and the location url needs to be shown on the event during the event itself.
