Navigation problems

So I’m having an issue with my sim setup.I’m running XPlane 12 with realism gear gns530 and reality XP along with air manager with dual G5s and the stock 172 in xplane. Everything works great. Except when I am flying a missed approach. After hitting susp to initiate the missed approach upon arriving at the missed approach fix to start the hold my G5 HSI does not flip to a to indication and change to the inbound heading. The only way to change it is to go tot he G% and manually dial the OBS to the inbound course. In the actual plane I fly everything flips automatically when entering the hold on the missed approach. Anybody have an idea on what settings I should look at to fix this. Really want to get my sim setup functioning just like the plane I fly.
