Thank you sixchannel and jford for your answers.

Sorry, I now found out, that what in the german version of BiaB is called "strophe", in the english version is called "choruses" - the number of repeats of the song.

The problem is, that BiaB newly doesn't remember the setting of the choruses. A song, saved with choruses "1", opened again, has always choruses "3".

Sixchannel, I don't mind to change it for each new song. It would be nice, if the standard-setting for choruses woud be "1" again. But above all I would like it to remember the setting for each song.

Jford, the phenomenon happens in both versions of BiaB, independent of the files exchanged. So if I save a file in my 2012-version and open it again, it has changed from "1" to "3". The same in the 2014-version. I just wondered, if one software has "infected" the other?
