Anybody experience Quicken changing Federal/State Estimate Payment Dates?

I have been doing year end planning, and when changing my 4th 1/4 Estimated Payment amounts for end of the year changes, I found that all of my previously entered and correct planned Estimate payment dates had been changed in Quicken Classic Premier R 65.17 build 27.1.65.17.

My January Fed 4th 1/4 2025 was changed from 1/15/26 to 5/15/26….similarly for the State (MN) dates. Also changed were the 2nd Fed and State payment dates from 6/15/2026 to sometime in October, and the 3rd Estimate dates reminder disappeared.

This is very bothersome, and makes me concerned about the reliability of my payment reminders.

I would appreciate anybody's help/or similar experience. I have re-entered the reminders for the correct dates, and hope they will stay there!
