Smartphoneone language ≠ discord language: timestamp

My smartphone's language is Dutch. As I mostly speak English on Discord, I've set my language to UK-English in the app. It works everywhere as far as I can tell except for the timestamps. As long as it's just numbers, it's fine. I'd like to not have to look at "Eergisteren" and such when scrolling through older messages though. Is this a bug, or can it be fixed somehow? Thanks!
