Btop varying between different decimal separators

For some reason, btop is varying between using a comma and a period. I don't remember when it started doing this but I've not found a way to fix this yet. All of my locale settings appear to be normal as well as no other program are encountering the strange issue. I've uploaded a screenshot of how the issue actually looks. Is there any way I can fix this or is this just how btop normally displays decimal separators?
