Creatures not seeking eachother out when breeding is enabled and activated ingame.

Details:

• Entity Model: (Custom java model) ModelDove
• Behavioral Characteristics: Creature
• Type: Undefined
• Check to make this entity breedable: [checked]
• (breed trigger) Items: Pumpkin seeds

What happens In-game:

Doves appear in-game and will display hearts when right clicked while holding pumpkin seeds.

Once 2 or more doves have been triggered with the hearts, they do not seek one another out to breed or produce another model.

Including workspace used. I am new to MCreator -and am not sure if I am doing something wrong or if this is a bug. A few people have asked about this issue in the forums and have gained no response.
