Service Hours attached to an Event

I added service time to a calendar event entry. We marked which people attended, but it did not add the service automatically? (I know I can go person by person with the “Expand” button, to manually add the service time; but I don’t want to waste time doing that when it should automatically add the time for us. This is NOT the first time this has happened.

TT- can you please get this buy fixed? Thank you!!

This has been reported however there is a relatively simple work around. In the Header column if you increment the number up or down by one then do the opposite it will fill down all of the users and the selected users will have that number applied to their record.
