Hello. I've done a few flights now. Always when I was on the approach, the FO said "Set Go Around Thrust" once I pressed a Keybind on my Yoke "Confirm checklist Item" or "Start Next Checklist". I press that keybind to trigger the Before Landing Checklist. Using "Confirm Checklist Item" to start the before landing checklist never worked for me yet, so I tried the keybind "Start Next Checklist". That one worked and it triggered the before landing checklist. But for some reason, when I was fully established, and didn't press any button, the ATS Fails. Once I re-enable it, the FO says "Set go around thrust". I'm not sure what I am doing wrong. Once I landed, the after landing checklist worked well, but simultaneously the "Immediate Return Checklist" was going on. So there were two FO voices talking over each other. I'm not sure what I am doing wrong here.
