FTH Attendance Reconciliation not working

I am unable to update the attendance for club meetings.  It's frozen.  

We need your club number to investigate.

club number 586030.

You modifiy the Attendance report by fixing the agenda for that date.

Apologies for not being clear.  I know how to update the attendance. I've done it many times before.  The issue is that I cannot change someone's attendance from "in person" to "online".  I'm not even sure if it matters how they attended.  It is a recent FTH change. 
 

Yes, there is a new parameter for meeting type in the agenda settings (templates) and on the agenda setup tab.  
The options in the attendance register are based on the setting for that dated agenda.  If it is set to In-person, you won't be mark anyone as attending online.or vv.   Only hybrid meetings allow either online or in-person attendance.
