Filters URL - weird reset

-- HikaShop version -- : 4.3
-- Joomla version -- : 3.9.21
-- PHP version -- : 7.3.22

Hello,
I use 2 different filter modules. Each of these 2 pages has its filter module.
Each module calls a different filter and a different menu redirect as well.
After a choice in a filter you can "reinitialize" the filter. After doing that, here are the URLs that are displayed:
1) www.mysite.com/accessoires.html?limitsta...es_1=&filter_Size_7=
2) www.mysite.com/boutique.html?filter_Cate...es_1=&filter_Size_7=

Strange thing, I notice in the url the name of the 2 filters activated from the Hika backend. "Size_7" and "Categories_1"
Why are the end of these 2 URLs the same?

Besides, if I publish a third filter (Size_3), without using it, well it is added to the URL:
www.mysite.com/boutique.html?filter_Cate...ze_3=&filter_Size_7=

how to get more friendly urls with filters?
Should I use a 301 redirect?

edit:
I am currently subscribing to the "categories_1" filter because it is irrelevant. I keep the second "Size_7" Wood species.
the "reiniatilsation" button generates a new URL

Thank you in advance for your advice
