Hi, all. I place the four RV-105 thrusters on the tiny tank, using 4-way symmetry, but Wernher won't let me click Next. I don't know why. How do I make Wernher happy? Thank you.

When I adjust the fuel levels in the rocket's tanks to see how the CoB indicator moves, the Next button remains inactive. I cannot click it and continue with the next step. Is there a fix for this? Thank you.
