Welcome to the Hubitat community, sorry you are having troubles.
What specific hub firmware version are you on? There have been many updates in the past couple months to address issues like this.
Have you done a rebuild database lately? That can help if a database is corrupted due to pulling the power cord or other unintentional power loss. Generally speaking, you never want to pull the power plug on a Hubitat or any computer for that matter.
The next thing you want to consider is if there are errors or warnings in the logs. That may direct us and/or support to an issue that needs to be addressed.
Please also read this and try the steps listed.
