Record escaping grouping

I have a table displaying appointments and they’re grouped by date and also whether the appointment has been confirmed. However, one of the records is escaping the grouping and I’m not sure why:

I’ve added the first column to show the record that has escaped the grouping does indeed have the field Confirmed as Yes.

Hey @Harry, bit of an odd one. Be useful to see what’s going on in the table and the page.
As you just down the road from me we can jump on another short Zoom and take a look.

@CarlHolmes That would be great thank you! I’ll drop you an email :slight_smile:

It appears to be forcibly sorting them by date/time. It doesn’t matter what groupings I do and what sorting I do, it is always sorting them by date/time.
