Compiling to RTF does not heed margins

I compile notes and other things to an RTF doc so that I can then print it out and put it in my writing journal. Now, I use a 5.5 X 8.5 sheet of paper so I change the paper layout and dimensions. I am now having an issue where in some instances, rather than the text falling to the next line when it meets the margin, it just goes off the page entirely. It seems to be related to the indent spacing, but I don’t know how to change that setting in Scrivener. I don’t see it anywhere, in fact. Does anyone have any advice?
