Cuts seem to not be flat

hello im sure this is an easy fix I have cut multiple projects with no problem but this one i seem to be having a little problem im showing the test piece instead of actual piece but same problems…I use a 1/4 downcut bit and it seems to cut flat but then in some areas its raised or makes lanes sorry not sure how to explain it the shapes look fine but using words brings it out.i dont have a no chattering or does the same with an 1/8 bit too

Have you trammed your spindle? Search tram, this could be your problem.
