Calendar selection reverts and does not remember my selection after I quit and relaunch

Smart Filters & Remembered Calendar Sets

You're likely using a Smart Filter with the Remember Calendar Set option enabled, which lets you quickly switch between different calendar sets.

When this option is on, toggling a calendar on or off in the calendar source panel will display an asterisk next to the Smart Filter name in the toolbar, indicating unsaved changes. These changes are intentionally temporary, allowing you to adjust individual calendars within a remembered set without permanently modifying it.

To make your changes permanent, you must manually save them. Learn more here.
