Cloned track in album title list

[UweD]

During playback of track 34, I cklicked on 35 to play, moved the mouse and wow... track 35 was dublicated in the list. I could not believe, so I checked if my audio files/tags were ok... no the problem exist within MM.
I am normally reluctant to write about "phantom bugs"... so I tried to check and seleted other albums and reselected this album, then the titles were back to normal.
I will watch it and report again if I find something or it happens again. I took a screenshot but have no idea how to upload it here.

Presumably this is unrelated to MediaMonkey Server?

What build (Help > About) of MediaMonkey did this happen with?
