I have two event types, one is correct and the second one does not count my availability correct.

My availability times are:

so until 8pm with an 90 minutes event

But the system calculates my last bookable time at 5:30pm => it should be 6:30pm

I've also double and triple checked my time limits and browser cache.
I've also created a whole new availability "work time" but it still does not calculate it correctly, but only for my second event type.. the first one calculates correct.
