Why isn’t the Draugr in co-op anymore?

I recently lost everything I had in Battlefield 2042, so Ive been grinding to unlock some equipment. I’m trying to rank up my Draugr, but for some reason, the F-35E is the only jet available in every map except Breakaway and Iwo Jima in co-op mode. Why can’t I use the draugr in Spearhead and other maps anymore?
