Rogue can't open lockbox

My rogue toon Feeniixx (Duskwood) is unable to open any lockbox. Very frustrating. All the lockboxes say they are locked when I mouse over them, and they indicate that a lockpicking still of 15 is required. ???

What level is your rogue? As you level up, your lockpicking skill levels with you.

Experiencing the same bug as of The War Within. I checked and their rogue Feeniixx is level 80. My rogue is level 70 and is unable to open a Leystone Lockbox that only requires Lockpicking (45).
