Quicken Classic Premier keeps mixing up my paycheck splits

I've been using Quicken Classic Premier for the last month or so. Been learning the ropes, but one thing that's been bugging me is setting up paychecks for myself and my spouse.

I have added both our paycheck as montlhy income reminders, and split them so that I can include the gross paycheck and itemize/track taxes, retirement, and so on whenever a paycheck clears. The problem is that whenever I close and re-open quicken, it seems the screw with the split and re-orders them, which also overwrite values for memos and amounts, throwing everything off. Not sure why this is happening or how to fix it, can anyone advice?

This Windows OS with version R60.20.
