We decided before the first session that my surface-born drow is NOT going to have the disadvantage. However, I can't get rid of it, and none of the modifiers (from ability or Proficiency) show up on the skill. (I have the same modifiers on Insight, those show up without problem) I tried to manually add the missing points, and DDB refuses to accept the override.

I managed to fix up my passive perception, which also lacked my bonuses.

I'm not sure if this is intended, or a bug or whatever, but I'd like to get rid of that disadvantage, please.

Make homebrew version.

Remove Sunlight Sensitivity trait.

Save.

For future reference, making a new subrace and basing it off the Drow doesn't help =3 I made my own, and then looked around on the homebrew market thinking that other, better people might have made it already, and lo and behold - the blue mark on Perception stubbornly remains.

I might try to build a brand new race for this poor character from scratch later.

Then something else is causing it because it worked perfectly for me. 

Also, disadvantage doesn't cause a blue mark. It causes a red D.

A blue mark means the skill was customised. 

To highlight what I mean about the blue check/red D thing, and show that yes, hb-copy and remove SS feature does work, I made an unlisted video. Apologies if I'm not speaking great, it's rushed and I have a major headache.
