Thank you for giving those steps and trying and letting me know the results. If you were unable to access the option to reset the cloud, it does not appear that this issue is related to syncing to the cloud.
At this time I would recommend contacting support directly for advanced troubleshooting steps.
Quicken Care has the tools to review and research this issue further.
1. Edit > Preferences > Quicken ID Sync & Alerts
2. Click the link to “Reset your cloud data”
Please let me know if the trouble persists after completing this step.
