Pigments showing duplicate variable entries in autocomplete?

Hi,

Whenever i type a hash to open all my color variables and pick one (typing the variable names doesn't preview the colors anymore...), I get two of every color. I ticked merge duplicate colors thinking that might help but nada.

Like so:

If you need a log or anything, could you let me know how? I'm very new to Atom :)

Edit: Just noticed one is using underlines, and one dashes - any significance there?
