UAV Log Viewer not showing 3D plot in some logs

Inside the UAV Log Viewer some logs show 3D plot and some don’t. Any ideas why? Initially, I thought it was related to the presence or absence of positioning data, but it doesn’t seem to be the reason, since some flies with visual odometry + hereflow generate a log file that doesn’t show a 3D plot, and other, in the same configuration, don’t.
