Filtering changes Produkt-Type and thus template

Hallo everyone, i’m very happy with woof product filter, but I would need your help on this problem.

I have 2 custom product-types : bike-buy(velo-kaufen) and bike-rent(velo-mieten) with 2 distinct templates.

When I first get on https://www.fateba.ch/type/velo-kaufen/, everything is fine and the correct template is loaded (taxonomy-type-velo-kaufen).

but when I use any of the filter, making the url https://www.fateba.ch/type/velo-kaufen/?swoof=1&product_cat=sport-und-gravelbikes&really_curr_tax=34-type, then the type is lost to “product” and the template archive-product is loaded.

Can I force a specific type when the url begins with https://www.fateba.ch/type/velo-kaufen/… ?

Thank you very much for your help.
