Volta Line Too Low For Higher Notes

[An incorrect draft of this inquiry, containing a large error, may have been posted - if it shows up, please ignore it. Sorry.] My score has a Volta Line Number "1", which is lower than, or bisects, some of the high ledger lines in the treble clef. The Volta Line bisects the third ledger line "E", which I believe is referred to as E6. It therefore appears lower than, or bisects, some of the notes, the highest one being the fourth ledger line "G". I can't seem to raise the Volta Line so as to cover those notes. Also, the "8va" mark appears at the same level as the Volta Line, so I can't simply enter the notes one octave lower and go that route. Is there a way to fix this? (The second Volta Line, Number "2", does not have this problem and does not need to be raised or otherwise fixed - what is your opinions as to whether I should raise it also, to the same height as Volta Line Number One, or leave it as is at its original height?) Thanks.
