When you give yourself an item with the CanDestroy oder CanPlaceOn tag, like:
/give @p log 1 1 {CanDestroy:["standing_banner"],CanPlaceOn:["wall_banner"]}
It says:
Can be placed on:
tile.banner.name
So the bug is that the translation for "tile.banner.name" is not implemented yet

Can I ask a question?
Where are the translations for other languages, I read they are in "%appdata%/.minecraft/assets"
But for me there is no "lang" folder
All the translations are meant to be in the lang folder.

Like I said I don't have this lang folder at the described location but other languages work fine, do you know where it is then?
