Difference in transmission one vs two delta functions

I'm looking at a potential described by two delta-functions, V(x)=V0d(x-q) + V0d(x+q). There is a particle coming in towards the barrier from the left with energy E. I have found the transmission coefficient for the double-delta-potential. And I can see that for some values of E,V0 and q the transmitted flux is greater than for a single delta-potential. Why is that?
