Hmm, thanks for the report. I haven't seen this, but I'd guess it involves Pawn taking over the green upgrade arrows in your bags. For now, if you go to the Options tab and uncheck "Show bag upgrade advisor," Pawn will leave those alone, and the game will show them just based on ilvl instead of your active scales.
Does the problem go away if you turn off that option? Do you use any addons that give you nonstandard bags, like Bagnon and others?
