 - Moved the data source settings into the data selection component.
 - Fixed the "send to" menu position, which was offset due to the MudBlazor 8 upgrade.
 - Fixed a rare issue with the enum selection component, where the `SelectionUpdated` function was not called for the special `other` enum values.
+- Fixed the new setting dialogs, which were not updated appropriately when settings were changed.
 - Removed the link to the ERI server assistant from its settings page, as it is no longer necessary.
