Yup. I don't know if it's intended, but when bringing the plate item back into inventory with the new-ish food items (anniversary cake, snowman cookie, christmas cookies, yule log, etc) they do not seem to get replaced in your food inventory. Also, the japanese food (from japan nexus) seems to randomly switch to another type (often ramen or rice bowl) which makes it unable to be placed on a plate again...

I believe before the food items (burger, hotdog, pizza) were replaced in your inventory when you deleted the food plate.
