Unable to start from gate with Simbrief flight plan

When I import a Simbrief flight plan into MSFS, I am often unable to depart from a gate. I start MSFS and load the flight plan from a local file on the world map. If I try to select a gate, it always jumps back to the active runway. This happens not always, but very often, in particular at larger airports.

A work-around is to unselect the departure airport and then pick the gate from the world map. That works most of the time, but not with the following flight plan
CYULCYYG_MFS_21Oct23.pln (7.1 KB)

I have the BM World scenery of CYUL installed. I can start from a gate if I do not import a Simbrief flight plan and fly DCT instead.

Thanks,
Peter
