Required Fields doesn't hide

Hi, I have this kind of setting

Field Type of Bday

CONDITION

Visible
- Exactly one condition must be true (XOR)
- Event Type , Value is, Bday

Required
- Exactly one condition must be true (XOR)
- Event Type , Value is, Bday

So, technically, the field "Type of Bday" should only be visible if the "Event Type" is "Bday" and it should only be required if the "Event Type" is "Bday".

Am I wrong/doing something wrong? Because the field "Type of Bday" is always visible even though I have this condition.

But if I remove the required condition then the field will be invisible.

Thank you!
