Francoisf30 Thank you so much for reporting this. I'm having the same issue in my game and created a video to help show what's happening for me.

The video starts after I had created the Gay Bar schedule, which includes a Bartender, Staff and Gay Client roles. None of these started with any Romantic Orientation role criteria. Once I added the Attracted to Male criteria to the Client role, the schedule was wiped out. I was able to reload the saved Gay Bar preset which only had one timeslot and did not include any Romantic Orientation criteria. I readded all the timeslots and then also added that criteria again to the Gay Client role. After that, I saved over the existing one. At that point, I was no longer able to load that preset at all.
EDIT to say that the video is from an unmodded save.
