Reseat the eyes and make sure they stay put when you reinstall the eye cover.
If it continues to happen then it's likely that you are not putting oil on your bolt tip and you are using a rubber tipped bolt. Friction is pulling the detent back and thus lifting the eye cover just enough for the eye wire to jump out.
A drop of oil on the rubber tip (or O rings) of the bolt should help with this.
Interesting, I hadn't heard of this.
