I installed the software update GC508 and I'm having problems with the engine page on the 737. Engine 1 starts normally but when I turn off the APU Bleed, turn on Engine 1 Bleed, open the Isolation valve and set Engine Start 2 to GND Engine 2 won't start. I have to use the kbrd shortcut CTRL + E to start Engine 2 but N1 and EGT remain at 0 until the engine starts, then they display normally.
