Elektron Musical Instruments

This question is about page copy.
Everytime I clear page 2, page 3 and 4 are gone.
Pasting from other pages onto page 2 makes page 3 and 4 gone too.
Simply nothing left on 3 and 4.
Other pages are fine.

I just up'ed to 1.06b.
It was the same when the machine was 1.05

Please help me.
