Since 2.15.40 the following highly relevant commits have happened, so
you might want to retry with current master, or with 2.15.41 once that
is released.  It is likely that your problem is fixed.

    Issue 2584 (redo 1967): please make partcombine merge slurs
    
    The partcombiner does not really bother about keeping the number of
    generated start and end slur events matched, so this attempts to cope
    by implementing the following behavior:
    
    a) multiple slur starts on the same moment are not an error but the
       same as one.
    b) multiple slur ends on the same moment are not an error but the same
       as one.
    a2) there will be a slur with direction UP if there is at least one
       such start event, and there will be a slur with direction DOWN if
       there is at least one such end event.  This might imply a double
       slur, but for ending it, a single slur end is sufficient.
    
    Consequently, a^(_( c)) (the second closing paren not required, just
    added for prettiness) will add a double slur.
