Not a Bug Pet ap reset did not work correctly

Description of the bug: i used pet ap reset scroll to transfer closeness points from a pet to another. i did it once and it was fine, but for the second time trying to transfer closeness from a dead pet to my current one, almost all closeness from the pet i was transferring just dissappeared. (my pet had 500+ closeness. first time i transferred from 1 dead pet that had also 500 closeness, i got +80 for my existing pet. I did this second time from another dead pet and the closeness from the pet i was transferring to went down to 133)
What is supposed to happen?: I an supposed to gain closeness on the pet, not lose 460 of it.
