more Crossbred confusion

1 Crossbred by definition is mating 2 different breeds so how can there be room for up tp 3 choices. That would be Mixed Breed.

2 So I have to choose one of the breeds for Breed and then list the other breed under Crossbreds right ?

3 How do I delete the breed when I have made a mistake ?

1. You can call it mixed breed if you want. There has to be the option to multiple breeds as some people have their model's breeds as fairly specific (ex. 1/4 arabian, 1/4 saddlebred, 1/2 paint)
2. Yes. Some people also choose to do, for example, Quarab as breed, then list the crossbreeds as QH x Arabian (another reason why it may still be worded as crossbreed for some). Either of these are correct.
3. Click the breed on the list again, it removes the checkmark and deselects the breed
