You didn't post the screenshot, so I can't see your dashboard.
Are you using a touchscreen device (like an iPhone, iPad, Android, etc.)? If so, those have a default feature called Safety Covers which prevent the outputs from being active until you unlock them to prevent "butt dialing" from accidentally activating an output. Do you see gray diagonal stripes across the sliders? If so, they are locked. Swipe your finger from right to left to unlock it, then you can click to activate it.
As for the Sw1, Sw2, etc., those are the six built-in switch ports from the round I/O port on the Apex where you can connect a breakout box. The breakout box can be used to attach float sensors, magnetic door switches, pressure switches, etc. If you don't have anything plugged into your I/O port, then those switch inputs are not in use and can be removed from your dashboard.
