Slugs of Kingdom Hearts HD 1.5+2.5 on lutris.net Website Doesn't Match

[manuth]

I have noticed that the game KINGDOM HEARTS HD 1.5+2.5 ReMIX on lutris.net now has the slug kingdom-hearts-hd-15-25-remix.

However, the result of slugify("KINGDOM HEARTS HD 1.5+2.5 ReMIX") in the current master branch is "kingdom-hearts-hd-1525-remix".

I assume this is most likely because the game is called "KINGDOM HEARTS HD 1.5+2.5 ReMIX" on EGS and "Kingdom Hearts HD 1.5 + 2.5 Remix" on IGDB (notice the absence of spaces at the "1.5+2.5" part in the EGS title).
