Switching from Honeywell to Emerson Sensi-fan issues

I switched our thermostat to an Emerson Sensi Touch from an older Honeywell model that stopped working. Previous configuration used the following wires: C, K, W, and R (see attached pic).

I used the K wire on the G terminal of the Sensi, but now the AC unit is running when the fan for the heat kicks on. Sensi configuration also attached for reference. Is there a better configuration or do I need an HVAC person?

Now also added a pic of the configuration at the furnace end as well
