You should start with a simple circuit containing only a single regulator. Put in a ramped dc (e.g. VPWL source) and see if the device is regulating.
When attaching the model to the symbol, you also have to assign the proper pin sequence. Your symbol has pins 1, 2, and 4. Your model has pins 1, 2, and 3, and I don’t know which is in, out, or adj. You have to check this first. Then you have to do the pin assignment.
Only when this single device is regulating properly, then add it to a more complex circuit.
There are 317 circuits available in Simulation examples for KiCad/Eeschema/ngspice.
