Waypoint not loading correctly in MSFS 2024 from Simbrief

I recently created the flight shown in the first image below in Simbrief. It has two waypoints BENGA and G270P. As can be seen this imports into Navigraph and can be loaded into Simbrief in the EFB MSFS2024 fine, as shown by images 2 and 3. On importing the flight plan as can be seen in image 4, G270P has been replaced by a geographic coordinate. I can delete this and find G270P in the EFB manually, so the waypoint does exist in the sim, it’s just not importing correctly. I have the latest AIRAC.
