Mystery snails have two different shell layers. The inner layer and the outer layer. (Only the outer layer can be striped, so if you see stripes, it's the outer layer you are looking at.)
I suspect what you are seeing are snails that have different colored inner and outer layers. Sometimes one layer grows faster than the other, and you get a border like you see in your photos. The other layer will likely catch up eventually.
You must be taking good care of your snails, for them to have a sudden growth spurt like that.
