[BioC] intermittent oddity in rtracklayer track names

I've tried hard to come up with a minimal example of this -- some fragment of code to reproduce the error -- but I haven't figured out yet how to do that. So instead, and thinking that a brief report might be useful, and will possibly trigger something in Michael's mind, I send this narrative email instead.
I create a track with this command:
track (session, 'exonHits') = grange # a GRangesForUCSCGenome object
Then I ask to look at the track:
view <- browserView (session, range.to.view, full='exonHits', dense='ruler', hide=trackNames (session))
The problem is that sometimes I get this error:
Error in resolveTrackIndex(x, i) : Unknown track(s): exonHits
When I look for the 'exonHits' track, I learn that there are actually two of them, each with a suffix: "exonHits m" and "exonHits p"
> grep ('exonHits', trackNames (session.sub), ignore.case=T, v=T)
exonHits m exonHits p
I can use these odd, modified track names, and display the desired:
view <- browserView (session, range.to.view, full='exonHits m', dense='ruler', hide=trackNames (session))
But it seems rather suspicious. Is there any reason for the 'm' and 'p' suffixes?
