multi-template site bug with product pages

-- HikaShop version -- : 2.5.0
-- Joomla version -- : 3.4.3

My website used to work quite well before the last update.

I have 2 templates, and the same products are displayed from 2 different menus. The first one is displayed only on the template A, the other on the template B.

In the template A i display the brand logo, on the other template , i dont ( it makes 2 websites: one for the dstrutors, and another for the final clients wich is not spposed to know the brand)

Since the last update, some of my products pages call the bad template ( i say "some" because strangely from the product list page, i can see differents types of links url to the product pages)

Even if i'm on a product list page displayed with a template "A", it genertes some links for a product page displayed with "B" template.

Hello,
We'll need more information to understand your issue, and help you fix it.
How did you restrict the displaying of your templates, did you restrict it regarding the menu that you were in ?
How did you access to you product page, so that we can now which link you used and on which menu you were ?

Thanks for the help.

I just found myself what did the mess: the update simply reactivated the canonical urls !

I access to the products list pages from 2 templates restricted by the calling menu link.
With a canonical url, hikashop just keep only one url in order to avoid duplicate content. But in my specific case, its a disaster

I just put the canonical option off, and now it works well
