Stallion Overbooking?

This may or may not be a bug, but is the system supposed to allow a booking request for a slot that has already been filled? I’ve noticed with both Final Scene and Quirky Scent that requests are coming through for slots that aren’t actually available, but I can’t modify the requested date on my end without declining and restarting the process.

I’ve also noticed this with Emoji too. He’s been bred for all his early slots, but it seems it’s still letting requests come through for them.
