Hole bar rest

[Bernard Meylan]

When I filled one hole bar (C) with a centered rest (R1), my next bar 
appear normally with the notes but also with one hole bar rest; as I use 
the (r1), my hole bar rest is normally not centered and the hole bar 
rest on the next bar is disappear. How can I have a centered hole bar 
rest without this strange (for me) problem?
