Most better chainrings intended for double or triple today have shifting gates. These are the cut down or skipped teeth, which along with ramps or pins are intended to improve FD performance.

For single speed (or 1x?) these gates are undesireable because there's no benefit to you, and they can be the cause of chains derailling. Look for a ring designated for single use, or any old fashioned (cheap) ring intended for mutiple use, but without the gates.
