Why does some varnishes shrink with Seche Vite?

I have never really suffered from the Seche Vite shrinkage. But this manicure really suffered from it. I almost didn't post it, but thought I may get some ideas as to why it happens.

Interested to hear from anyone with an idea.

For those interested this is Dior Vernis 694 and Nubar White Polka Dots
