I'm afraid this issue is not solved with 3.1.5.
Center told me to descent to the same altitude every few seconds. After handoff to Approach Approach continued to do so.
Another oddness: With the STAR option activated, I was first cleared via a STAR (reading the name that was specified on the SIDs/STARs page). Shortly after I was cleared to final at pilot's discretion. And then I received vectors. If I didn't miss something that was without a runway change.

Another flight today and no problem with repeated descent instructions on this flight.
The only thing I did different was to define a STAR entry on the "Adjust altitudes, SIDs, STARs and Holds" page that was not the last waypoint.
I attach the logs for this flight too, just in case it might be helpful.
