Not sure what you are asking, are your primers being marked/dented? I doubt if it is a problem, depending on how severe the dents are. I would not grind the seating stem or anything as it would affect the seating depth, which for many new reloaders is often a problem. Inspect the primer seating"stem" and see f there is any burrs, or gouges. It may just need cleaning. I believe primers are "standard dimensions"; large rifle primers should all have the same diameter and height so the Lee Loader will work with any Boxer primer...
FWIW I like Lee Loaders and even though I have 4 bench presses, 16 die sets and 1.27 tons of assorted reloading equipment, every once in a while I'll get out one of my 7 Lee Loaders and pound out a few rounds. I don't have any problems popping primers as I worked out this problem in '70 (I made sure all the spring loaded plates in the priming base were clean and free, and the stems were centered, smooth and clean. II also found a dead blow hammer worked better. I had one kit the would pop mebbe 1 out of 20-25 primers, my 44 Special/Magnum kit. I fixed that by lightly chamfering the primer pocket, just like I do for removing military primer crimps and the problem went away.).
I've learned how to stand on my own two knees...
