Langswitcher adds "/home" to alternate language links

Hi all,
I have installed langswitcher on 2 multilanguages websites and all is OK, including using slugs.
On a 3rd website, except on home page, langswitcher is adding “/home” to alternate urls.
When I am on a French page, this is what shows:

[code]

[/code]. The /home is also added to the FR or EN alternate links but nowhere else in the navigation.

It seems to be created by “rawRoute” in $data->page_route = $page->rawRoute(); of langswitcher.php but I cannot find how to remove this “/home”. I compared site & system config files of different websites, reinstalled plug-in… but cannot find how to get rid of this /home…

Any idea how to remove it to avoid duplicate links and redirections ?

I come from self-taught html/css and enjoyed working with Grav during the past 9 months, including theming. Thanks for the good work of all, including on tutorials & forum: 1st time I need to ask!
