More numbering trouble with blocks

Dear all,

when pairing exercises with recalled solution blocks it seems that  
both are numbered consecutively
but independently.
When I don't give a solution to an exercise, the subsequent solution  
numbers are incorrect.
What is the proper way to deal with this? Manipulate the counter in  
the exercises without answers somehow?
Basic example attached.

Thanks,

Matthias
