Whole Measure repeats and Rests

[Joe Wilkinson]

    Hi Richard,
    Happy Christmas.
    
    Whole Measure repeat seems to take over somewhat.
    In these staves the first is 1 music then 7 rests
    The second 1 music, whole measure repeat, then rests
    The third has 2 Whole measure repeats two rests then 1 music and
    finally 2 rests.

    The Typeset is below and, apart from staff 1 all rests are Typeset
    as Whole measure repeats. 
    Even the introduction of some notes in Staff 3 does not change
    things

    Looks like a bug.
    Joe
