某些论坛上，徽章页面显示 NaN 而不是数字

On some Discourse forums, for example Python and iNaturalist, NaN appears instead of a number on some pages related to badges.

See iNaturalist Forum: NaN instead of a number on badge pages.

I can see it here on Meta too. For example on https://meta.discourse.org/badges/114/bug-reporter?username=nat

I must be overlooking something, because it looks to me as if both parameters are available.
