Where are you attaching your gauge hoses?
Are both of them on the service valves?
Are you familiar with how the refrigerant flow works in a heat pump heating cycle?
Instead of learning the tricks of the trade, learn the trade.
You're not connected to the low side, you have both gauges connected to the high side.
Connect blue gauge to the suction port.

You say, long story short. Its more like long sentence, no periods.
Connect blue hose to the third port!
Connect red hose to Large line port, heat.
and red hose small in cool.

I agree. I dont think youre on the true suction.
