Leading in PDF Forms not working

hi there,

I am working on a PDF Form and I find that I can only adjust the leading when I am in "entry" view - meaning, if i was the client filling in the PDF.

I can't seem to save this setting. When I make the change as described above, it works, but when i save, reopen the file, it's reverted back tot he default. My form has lines in it, which I need to keep, but when type is entered, the lines sometimes end up in the middle of the copy. When I adjust the leading to match my InDesign file, the type sits perfectly, but I can't save that setting. I can't direct my client to go into settings and change this as they are working, which seems to be the only way I can adjust the leading (out of "Prepare Form" mode)

I hope that's not confusing. Any help is sooo appreciated!
Thanks!
