Auto Load State Not Working With Some Cores?

I’m running Retroarch on a Shield Android TV @ 1920x1080.

So if I enable Auto Save and Auto Load State, I get crashes from certain cores when they try to load (saving works). One major example is the PPSSPP core. If I manually load the auto state, there’s no issue, but if RA auto loads it, RA crashes. This has happened on at least one other core although I can’t for the life of me remember which one it was. Other cores work fine.

MAME has a similar problem but it gives me a “error loading state” message or something to that effect.

Is this a known bug or am I doing something wrong? If it’s a bug, can I disable auto loading for only those cores?
