Guild Wars 2

Having my backpack full of dropped items I’m not able to sell most of them, not to the vendors nor the auction house. Take in mind these are not karma-bought items or not even soulbound quest items, just random drops. I can’t even sell the iron ores.

Is this a bug or I’m missing something?

Those blue bags you have are invisible bags, which means the items in them will not show up in vendor tabs, TP or be affected by Deposit Collectable.
