Looks like the old food bug is back! Remove the food, check your stats, eat the food and see if the stats actually changed regardless of what the tool tip shows.
If it doesn't change with the food then the food bug is back.
It’s always been like this for me on Xbox - 0 stamina bonus + 0 health bonus or whatever. I trust it’s just a display bug as my stamina, health and magicka bars stretch as expected.
I've seen this too. I also got lit on fire in a BG the other day (burning status effect) and the tooltip in the character sheet said it had a duration of 2 days or something.
