Learning bass, I see a lot of songs that have DD checked that don't actually have DD. And when I attempt to leave a comment on that song, even though I am logged in, no comment is saved.

 

I find that there are a few songs that I don't need some DD on, but at my level, that's rare.

Check for an alternate bass path on that track. A few charters have put non DD in the main bass chart and DD on the Alt / Bonus bass only.
