Filter not counting all products even after reassembling data, disabling cache..

Hi and thank you for your great plugin,
I’m sorry since I tried the usual things before opening this support ticket like disabling other plugins, clearing caches, reassembling products data,…
Unfortunately as you can see at the linked page, I have 44 published products but filters in the sidebar keeps showing only 20 products.
For instance if you try filtering per Model year 2021, you will actually see produtcs with “2021” attribute even if in the sidebar the count is zero.
Any idea?
Best regards
