Letters ”ge” after the “mis” files

[Ham920]

Two of the scenarios I downloaded, Battle of the Barents Sea and Battle of the Sibuyan Sea, both have the letter ”ge” after the “mis” files. When I place them in the single mission folders they don’t appear when you bring up the Quick Mission menu. I realize these are scenarios for German subs in the Atlantic. What more must I do to have them appear in the Quick Mission menu? Are there other components I have to download and place in the game? Thanks for your reply.
