FOM Will not Feed Several Pets (Possible database issue?)

[Yinepuhotep]

Level 110, attempted to feed corehound. Have the following in bags, all of which the tooltip says "Corehound loves to eat this.", and all of which the corehound happily eats when fed using the pet utility command:
Big Gamy Ribs
Fatty Bearsteak
Lean Shank
Scallion Kimchi
Honey-glazed Ham

When attempting to feed, it does not feed the pet, and pops up text that says "Your pet doesn't like that food."

Tested whether it's a level problem by feeding Pterrordax and Diemetrodon, both of which ate their food on the first try.

There was no error message on screen or in Swatter.

Tested with several other pets. Same problem appears with basilisk, nether ray, spider, devilsaur, chimera, and every other pet whose primary diet is meat.

Continued testing indicates there is no problem with any pet that does not eat meat. At least, not so far on any of my characters. Mostly seems to happen with pets that eat Legion and BfA meats.
