Menu - Categories Listing - Languages (BUG)

-- HikaShop version -- : 5.1.0
-- Joomla version -- : 5.1.1
-- PHP version -- : 8.2.19

Main Menu
- ITEM1 Categories Listing L1 / Language: Lang 1 / Calls Hika Main Category named CAT L1
- ITEM2 Categories Listing L2 / Language: Lang 2 / Calls Hika Main Category named CAT L2

Menu Associations for menu ITEM1 & ITEM2 is set
Lang1: CAT L1
Lang2: CAT L2

If I click menu ITEM1 "Categories Listing L1" - CAT L1 is listed
Then I switch to landing page, I change the language and
I click menu ITEM2 "Categories Listing L2" - CAT L2 is listed

This works correctly

BUT -
If I click menu ITEM1 "Categories Listing L1" - CAT L1 is listed
when I change the language in Joomla
- Listing of the CAT L1 is not changed to Lising of the CAT L2 = THIS IS a BUG!!!

Note: Menu association is set correctly - see the image please

OK, because this is an important - here it is:
