Pretty simple one, honestly. I'm playing a druid and I'm using the option to sell soulbound items that I can't equip. I noticed that I had a soulbound polearm that I couldn't use and, at first, I thought it might just be that I didn't have the proficiency. A quick search and I found that this feature wasn't added until later. Please update this addon so that it properly reflects druid's current proficiencies.
