Editing Estimate

Hi, I created an estimate and saved. I then went back to edit it and the estimate got all screwed up by putting each line item on a separate page. Now my estimate which should have been one page long with four line items was four pages long.

What went wrong? Is there a fix? I ended up having to delete the invoice and start over again. This is not good as it wastes one of my estimates/invoices per month.

Thanks,

Tanya
