The Beats To Cue setting that shows how many beats until the next cue actually shows the beats until the next cue OR beat marker. Since beat markers are no longer considered to be cues I would expect the beat markers to be excluded when calculating the beats to the next cue especially since when viewing cues you can't see the beat markers.
In the screen shot, the left red arrow is the play back head, the right red arrow is the next cue which is 8 beats or 2 bars of 4. I have bars per phrase set to 0 so I should just get bars and beats displayed. The -1.3 should say -2.4 or -3.1 just before reaching where the playback head is.
