Actually, that's also kind of normal on a new kit. When all the plastic parts are new and raw, powder sticks to them real easy.
After you've used the setup a while, it'll "break in", which means to say, the graphite in the powder will build up and coat the system in such a way that stuff stops sticking and moves smoothly.
Same thing happened to me when I first got into reloading years ago, after a bit of use it resolved itself, and it pretty much never happens to me anymore.
