Summary:
In English (US), the items Cooked Chicken and Baked Potatoe are called Cooked Chicken and Baked Potatoe just like in Java Edition. But when converted into English (United Kingdom), the items are still called Baked Potatoe and Cooked Chicken, unlike in Java where the items are called Jacket Potatoe and Roast Chicken.
Steps to Produce:
Change Language from settings main menu into English (United Kingdom)
Open world
Obtain cooked chicken and baked potatoe
Same case on Windows 11.
I should also point out this is the 3rd time translations got randomly screwed up, that I noticed either while playing or on media, with previous examples being cherry “execution“ sign in a far east language (IIRC korean, but correct me if I’m wrong), “International game design“ in czech (linked below) all within the 3 year span since Java+Bedrock bundle got announced. There are also countless more reports if you search “translation“ in the bug tracker.
Your translation model clearly doesn't work well and shoud be addressed. Translations strings for stuff that wasn't even touched should not randomly change.
