Satchel of Helpful Goods - Gives me only gloves as reward

My satchel of helpful goods has provided me with a set og gloves ever since lvl 20, I am now lvl 33 and still keeps giving me gloves as the reward. I am expecting more of a rotation between items but it doesn't seem to happen anytime soon. I need to know if this is bugged or not. I can recall one instance where I got the satchel delivered by mail since my bags were full and ever since that one time it only gives me gloves.

Loot from satchel up until this point: 2 belts, 5-15 gloves.
