Event Module - Tracking delegate acceptance (leads) not working

When adding a lead as a delegate on an event in the delegate subpanel; the “status” and “accept status” are blank, and when changed to accepted they stay blank.
Everything works fine for targets and contacts.
The database values are being updated properly and the SQL looks fine, it is just not showing up on the page.

Any insight on debugging this issue?

Hi Chris,

This may well be an Events module bug.

Thanks,

Will.
