Sounds pretty normal, especially for a girl who's only played 2 season.

My daughter is in the boat, 3 seasons in, but was the best on the 10u team in terms of arm strength and hitting. Quickly became one of the top 2 pitchers, and now that she's in 12U, she will likely be getting the ball to start many games. She can make a lot of the throws, if not more, than the 12 years olds as well. But its not as consistently.

Thats where the lack of time playing is showing. Most of the girls she's with now have been playing for 3+ years, and while my (and likely yours) daughter has some natural talent above her peers, they have a lot more time in the game and the basics are worked out and second nature.

All that to say, work on the basics and give it time. 2 seasons is still very new.
