Strange behaviour in hika menus

-- HikaShop version -- : 3.0.1
-- Joomla version -- : 3.6.5
-- PHP version -- : 7.0

I m trying to understand why in two different menus with the exact same configuration (menu settings, and hika category settings) I have differnt url. Some of my urls when I click on a hikashop category have ids inside, and others have a clean url , the same with the Joomla menu.
I cleared cache, deleted all canonical urls everywhere, I even emptied some tables that could probably cause issues but no chance.
What am I missing here.

Nicolas , san u pls check it. Its none of these reason. I cleared everything, checked db, emptied canonicals everywhere.
I ll send u admin access

its ok now. I dont know why, but yesterday it was off. Or your Ip was blocked.
2. If you find the reason, I ll be more than greatful if you find why when I add something in the cart and then I login, the session is lost and the cart goes empty.
I tried all solution that I read on the forum. The day before yesterday by anabling the system cache and moving loging on top of the order in the checkout it worked. Cart stayed, But yesterday again the same. I tried to do again the same steps, but nothing

I found the solution with the cache (disabled legacy) all ok with that. But I ll never find the other with the canonical first mentioned.
Thanks!

I remarked that any other settings in "Force canonical URLs on listings" beside "No, generate the urls", is buggy, When you click from the listing to see the product you re redirected to index.php.

I m in. Please check from another ip , or give me the ip

New update.
For now we discovered that there was an htaccess issue , and the redirects from that htaccess caused the problem. So no ned to search that.
