Simulation: Can't change analysis type

Description

When you select a type of simulation, let say transient, and run the simulation, changing it back to say AC simulation and running doesn't work. It still runs for the previous analysis type. You have to close the simulation window and do everything from scratch.

Steps to reproduce

Run a transient simulation, without closing the simulation window, run an AC simulation
