Which brands are you using?

Can happen due to the weight and perhaps you applied it too thick so sets like a glaze and then the nail might have moved or can move creating tiny cracks which if they apply clear regular nail polish [emoji140] you won't see it.
This happens to my one client when ever I use white on her it cracks no matter what brand so I given up and banned her from using white hahaha
