If it is a blank space rather than greyed out measures, then it would be as Ray said that a part marker is forcing a new line.

However if it is actual grey measures, then it is either

1) Most likely the bars are beyond the end of the song chorus --- increase the End bar of the chorus at the top of the screen --- default is 32.

2) The song has a Repeat/1st/2nd/Ending defined and the grey bars represent the repeated section. They will be hidden in FakeSheet mode is turned on.
