Nest learning thermostat wiring issue

[NathenB122022]

I have been unable to get this thermostat to reliably run our Trane XV95 heating/cooling system. We originally had a Trane thermo stat (model ) with the wiring format listed below.  I have also included the wiring per the nest app that i have followed.The system does kick the compressor on but the compressor disengaged after 15-30 seconds before attempting to re-engage (does this in a loop). Thoughts? Thank you!

Original Trane 

Wire 1: W2

Wire 2: G

Wire 3: W

Wire 4: B

Wire 5: Y

Wire 6: R (with bridge to RC)

Nest Wiring:

Wire 1: W2 aux

Wire 2: G

Wire 3: W1

Wire 4: O/B

Wire 5: Y1

Wire 6: RH

Take the wire you have connected O/B and move it to C on your nest.

Ate there some terminal letters under the connectors labeled Heat Pump?
