Minecraft Version: 1.18.2

(CallableHorses 1.2.2.5, CarryOn 1.17.0.8)

Expected Behavior

Horse teleports to user calling for it and does not duplicate if shift-left clicking

Actual Behavior

Horse is duplicated if user shift-left clicks fast enough

Steps to Recreate

1. Install both Callable Horses and CarryOn
2. Create a personal horse
3. Call horse from teleport distance while shift-left clicking
4. Horse should be cloned, leaving two horses, each considered a personal horse. Killing one of the horses will leave the user unable to call a horse, while also disabling the ability to reclaim the original horse.

Also happening with Minecraft 1.20.1, carry on 2.1.2.7 and callable horses 1.3.0.1.

Can confirm that it happens on 1.20.1 with callable 1.3.0.1 and carry on 2.1.2.7

Found a solution; just change the carryon keybind
You'd have to hit the keybind, crouch, then right click though
