should I try lubing the expander button a little bit before resizing the brass?
Lubing the inside of the necks does one thing, masks the cause(s )of problems. Dirty brass would most likely show up both ways, when the brass enters the die and when it pulled out.

Before you go any further give the die a good cleaning inside, a piece of paper towel with WD wrapped around a bush will be good enough. Make sure it goes all the way into the neck portion of the die.

Do me ( you?) a favor. Back the die off so it only partially sizes the neck , maybe 1/2-3/4 of it but before the neck-shoulder junction w/ the expander installed. If you paint the outside of the neck with a Sharpie you'll be able see how far its being sized.

Give that a go then get back with the results.
