Usually no, unless I’ve left a reply disagreeing then someone else comes along and downvotes them, makes me look like an ass who downvotes anyone I disagree with. I also check my own comments to see if people agree with me but I’ll keep the comment up either way, if I do change my mind I’d rather leave a new comment or add stuff in an edit.
It’s not too difficult to bot votes on lemmy so they’re even more pointless than they are on reddit.
There’s plenty of examples of software doing this right and displaying each language in the selector in that language, it’s hard to say why they’ve localised it here. Most likely they just didn’t consider how the user interacts with that element and localised it the same way they translate everything else, but that could be down to anyone from the developer habitually running everything through localisation to company policy where they couldn’t get an exception for that element.
You’d have to ask support for whatever software you’re using for more detail, chances are you won’t get anything useful back but if you’re lucky they might fix it.
