Using the solve function in Prime 3.0 with units not working

Hej

I just downloaded Prime to try it out, and i like the layout and general feel a lot better than MathCad15, but I've run into a huge problem.

I used the symbolic solve in 15 a lot, solving for a missing variable in an equation, where all others were defined with units and then using the normal '=' in the evaluation tab. Then 15 would combine the units and spit out a useable result, where I could change the units by writing the desired unit on the end. The picture below shows what i mean:

Now trying to do the exact same thing in Prime 3.0 gives me the following

Any help would be appriciated!
