Share 'Why do certain ganaches leak out of molded pralines?'

I have two ganache formulas that consistently leak out of the caps when I use them for shell molded pralines. One contains amaretto and the other is a lime/honey/ginger ganache. Both are delicious and I'd like to use them in my products, but no matter what I do, they leak. Since I don't have this problem with other shell molded pralines, I'm assuming that this is a problem with the ganache itself…
