"Muay Thai Fighting" - displayed points confusion

I've noticed that the points to enter/the game's worth in points differs from page to page and also compared to the Steam store.
While the latter might be a database update issue, the first seems quite odd.

It's 10 points on the Group's page, 50 points on the won page, 10 points on the giveaway's page and 6,99$ (with no discount) on the Steam store:

EDIT: Closed, because apparently this is an ESGST issue.
