Hi, thank you very much for your feedback and time,
No problem for the URL, how did you notice that one URL use the archive page and not the other ?
And the solution you provided is good but since the page is not full-width by default (we need a max-width because of products),
the header to will not take all the space available.
From you last message, you asked how did I knew that the archive page is using a Toolset template or not? I open the developers' tools in my browser and I check if the generated div/element has an ID of a template or not 😉
