Trouble with brand new dcc turnouts

[Newegineer]

Some of my newly purchased dcc turnouts keep derailing my diesel engines.  track is level, I did feel a "ruff spot" (like if you did not connect two tracks together correctly) I saw a few notices online regarding "filing down" a part of the turnout but am not sure if that is a wise thing to do.  Anyone else run into this issue with brand new dcc turnouts and how you were able to repair it?  Please advise
