downloaded scenarios not showing as "installed"

[Celeborn]

My apologies if this questions has been asked two or twenty times before.

Some MP scenarios I have put in my folder still show as red with "not installed" message when I try to create or join an existing game.

Anyone have any idea why this is?

I've had this too.
If I remember correctly I moved the scenario to the official scenario folder as a workaround.
