Problem
The Available in centres field is not shown on the edit screen.
Possible cause
The Available in centres field is only shown when creating a new drop-in type. When editing an existing one, centre availability is managed separately from this screen.
Solution
It is normal for this field to be absent when editing — this is expected behaviour.
Centre availability for existing drop-in types is managed from the drop-in type's details view or via the centre settings.
Contact your administrator if you need to change which centres can sell this drop-in type.
If the problem persists, contact support and include details about:
Which drop-in type you are trying to edit.
