Well yeah atm the mobile masteries is a bit bugged. The masteries does not tally out previous level exp. For example, if you level up from level 0 to 1 with exp 2874 of 2400, the game will starts over at 0 out of 10000 for level 1 to level 2, while the displayed numbers shows 2874 of 10000. It means the user will only level up on 12874 exp, not 10000

So for your HD ammo mastery, you are probably leveled up with 3000 or 3400+ exp. That is why when you said you are at 12500/10000 but only have 3/4 bar, the only reason would be that.
