404 from front-end javascript files when in admin template list

[Cameleon]

Joomla : 3.6.3
Virtuemart :3.0.18

Good afternoon,

I've currently five 404 error in my console when i'm in the admin panel. These are front-end javascript files from virtuemart.

I don't really know why they are called here, and i don't know why the language alias is used in the url.

How can i fix this ?

Regards,

Bruno
