This is niot a bug in BB, this is a bad songfile. BB is only doing what was entered and saved in a wrong fashion.

Improperly entered songfile.

Free internet downloads are notorious for such things in them.

It is also possible to do it to yourself by the way in which Edits are improperly made. In Notation Edit View, for example, one can RightClick on a note, select Edit Note and uswe the Spinner to change Duration value (or they could open the PianoRoll view and drag the Duration value, same thing under the hood) and thus increase of decrease a note duration such that it now "sounds right" but what you see is exactly what can happen, until regenerated, the original notation as saved will be there first.

Again:

If you Delete those offending notes and Re-enter them properly, then Save the songfile, it should fix the problem.
