No Autopilot on Return flight when programmed on MDCU from Simbrief

Hey everyone little help!

I’m Currently using simbrief and fly by wire a32nx Mod.

My issue is when I set up my flight plan from the main page of Flight Simulator for example KMIA to KSFB and load flight plan from Simbrief to MDCU … autopilot and approach are fine.

Once I’ve landed and parked… I now load my new flight plans from Simbrief to MDCU… going from KSFB to KMIA

I Check my

FUEL
PAYLOAD
CRZ
RAD NAV …Etc
I even verify my F-PLN and add my ILS runway!

My problem is once I’m in the air and click on Auto Pilot my plane (a32nx) doesn’t follow the flight plan and ATC doesn’t tell me to reach my cruise altitude… have to fly manually!!! Can’t see flight plan on MD screen on ARC but I can if I switch to PLAN.

I’m a newbie please take it easy on my but very eager to learn, Thank you in advance
