The price cursor disappears after applying a filter

-- url of the page with the problem -- : sofleurs.fr
-- HikaShop version -- : 6.4.1
-- Joomla version -- : 5.4.6
-- PHP version -- : 8.3.31

Hello,
I have a filter with a drop-down menu for selecting colours, a text field for keywords, and a cursor for a price range.
When I select a colour or enter a keyword, or when I choose a price range and then delete it, the price slider no longer appears (see attached image)
I haven't found a setting to fix this problem – do you have any ideas?
Thank's
