What's the issue? Please include any error messages you receive and as much detail as possible.
i filtered my lions to show me lionesses in heat, and it showed me two (jay and stella). so i went to request a stud, but in the drop down menu i noticed another one of my lionesses in heat was listed to breed (kaya). however, when i filter my lions to show me ones in heat, kaya doesnt show up at all. so now ive missed two days of her heat by accident :(
