How to solve a problem with standard 3-part check printing where the sample check setup is perfect but the actual check only shows the top part, not middle or bottom?

I read the tutorials and spoke to support but the issue was not resolved. I was told to just create the same check 3 times and then it will show all three parts in print. That worked BUT I'd need to create each check 3 times and then delete the duplicates - seems like a lot of trouble for printing one check. We never had this issue with the desktop version, only since switching to QBO.
