random marks or elements on the staff

When I change the number of beats for a measure, for example from 4 to 27 (for chants for church music) I get all these random vertical lines that do not go away and interfere with the music I am writing. Also, I am writing for 4 voices, and sometimes in one of the voices, a rest will not disappear when I have filled the measure with the appropriate beats. They print out and make the music look funny.
Also, is there a faster way of moving the text within the middle space of the system which does not involve clicking on each word and moving it? I tried to find a way to move the lyrics indicator, and looked for it in the help, but could find nothing.
Thank you for having a much easier program to use than what I was using before!
