Mobs created with the minecraft:as_adult command do not have some functionality!

Hello yesterday while creating my map I realized that creating a sheep with this command /summon sheep ~ ~ ~ minecraft:as_adult I realized that the sheep could not be sheared and could not eat the food given by the player. Then I also tried not other mobs and I realized that I can't do anything. I can only kill them. Please fix this bug thanks!

(I'm sure the problem is minecraft:as_adult)
