Multi-measure rests cause text and key change disappearing

Hi everyone!

I'm writing a part using MuseScore 0.9.4 on Windows.

I noticed this bug when I use multi-measure rests:
I insert a series of rest measures and I put on the first rest measure a key change and a text.
Then I go to the Style window and I enable the multi-measure rests.
The multi-measure rest is created but the text and the key change on the first rest bar disappear.
If the multi-measure rest is in the beginning of the part only the text disappears.

How can I solve this issue?

Thanks in advance
