Anyone else having trouble locking their weapon mastery styles?

I swear I keep locking my mastery styles and imprinting in my armory but it keeps chosing a certain type of weapon style automatically.

i've noticed that it unlocks my secondary weapon style randomly on Armory switches.

Nope, no issue like that here.
The only glitch I've come across is when changing from one armory to another with a dual weapon, the colors vary in each hand. One hand is correct, and the other hand defaults to color pallet 1, 2, 3 in each slot respectively.

Yes, I've seen the same thing. For whatever reason, one weapon will be one color while the other is a different color, almost like one hand takes on the primary color palette while the other takes on your selected color choices. The only way I've found to fix this was to make all three color options the exact same color.

yeah I keep getting fireman axes instead of temporal rods -.-

Someone mentioned entering PVP instances was the event that reset them. Also not being locked into Armories. I have the exact same thing happen constantly on Primary and Secondary WM Styles.

That happened to me some months back

Yep, I've seen this issue...
