Slime breeder create hostile slimespring

I lock those breeder into a small house, just near the river, and I going sleep into the ship on the river, the next day when I wake up, only found out there’s 3 hostile slimespring right on the river bank. and when I approach. they actually attacking me, so I destory them all,

wasn’t support the slimespring are friendly toward the PC? why they are attacking me? is this some kind of glitch or something? wasn’t the blob are support the one who aggressive toward the PC?
