"Chipped" Side Seals

"Chipped" Side Seals
I pulled my motor apart because I lost compression, and I found I had warped apex seals. That's a fairly common problem, and I think I know the cause -- too much heat and too little pre-mix.
While I was going through all the other parts, I noticed that most of my side seals had a small chip. Effectively the tip of each seal that was in contact with the side housing was gone. I have seen this in pictures of other engines.
Is this common?
Is it a problem?
Is the cause known?
Since the clearances are good, I'm considering just flipping them over and reusing them, so the chipped side is down in the slot. No sense replacing replacing them if the same thing will immediately happen to new ones.
