Welcome to the forum, @zeludo.
Are the baskets of carrots closer than the vegetable stews to where the hearthlings are?
This problem has happened before, but I’m not sure that it’s a bug. But they should be eating the stews anyway (you could try removing all the raw food and see what happens).
There’s a discussion about it:

I also agree that they should prioritize cooked food. The fact that they are complaining is inavoidable in this case
