Sort is not working. The menu show many times the same option

Hello! thank you in advance for your help
my website:

I’m new with algolia

my “sort” menu show many times the same options in place of the selected ones


it’s in french, but the problem was the same before my translations


This was answered via email, but for anyone stumbling on the same issue, reinstalling our front-end code through the Settings tab of the app > Install in a new theme should solve it.
