[BUG] Adventure (within Collection) not being saved after adding Visit

[AadNL]

Describe the bug
When adding a Visit to an Adventure in a Collection, the Visit is listed under ‘My Visits’ but the Adventure won’t Save (& Next) unless ‘Constrain to collection dates’ is being enabled.

To Reproduce
Steps to reproduce the behavior:

1. Edit Adventure in Collection
2. Add Visit to that Adventure (i.e. add start-date, end-date and click Add) N.B. Constrain switch is off
3. Click Save & Next
4. Adventure is not being saved, instead the new visit start date gets focused (cursor moved to start day and start day highlighted).
5. Adventure only gets saved after Constrain is switched on

Expected behavior
Adventure is being saved with new visit (without need to switch Constrain on).
