Via's connecting the wrong layers

Hello,

Im running OrCad PCB Designer with Pspice version 16.3

Im making a circuit that runs lots of current through it and they need to be connected on both layers. My plan was to do this making lots of small via's. It wont let me double click and make a new via. So i tried copying and pasting a previous via. When I do this, it connects the wrong layers, infact it always choses the same layer, my ground layer.

Is there any sollution to this?

Thanks in advance for any help.
