I have the same blank lines problem in my register starting today, June 1, 2022. I can't delete the lines. If I try to enter info on these lines, the date defaults to an odd date and there is no save button on that line. When I go to close Quicken it asked to save but never does. The extra lines are only in one account register, all the other account registers are fine. I have tried to follow your Troubleshooting 101 and downloaded and installed Quicken again, also tried the Mondo Patch. Rebooted the computer. Still the extra 4 lines in the register that I can't use. Thank you.
