How do i remove file-maps?

I accidently added same map with movies twice.
*Movies (2)

So it takes very long time to scan all this.

But i cant find a way to remove these file maps.

Do i have to have to start over and install OSMC from scratch?

Invoke the context menu, delete the share you don’t want and clean library



I found some more menus thru original skin.
But I am sorry to admit i do not find(/understand where to find) any delete function.

I choose. Videos -> files -> it lists my maps… what do i do next?
