When adding availability and enabling the overlay for "everyone's availability", the own selected availability range is not scaled correctly then the selected time increments are anything other than 15 minutes. In my example, I selected one hour as increments, which resulted in the selection from 1 PM to 2 PM showing as 1:00 PM to 1:15 PM.
Overlay disabled: here my availability is correctly marked

Overlay enabled: here my availability is incorrectly scaled by a factor of 0.25 = 15 minutes / 60 minutes
