How to uncheck all To Do Tags in OneNote

Sometimes we want to reuse the To Do Tags in OneNote, we can use "To Do Tags" feature to re-tags the To Do List.

Re-Tags the To Do List

1. Select the To Do List ( all checked and in completely status ) in current page.
2. Click the "Home" tab -> "Tags" group -> "To Do (Ctrl+1)" feature to remove all selected tags. ( In this way, we have to remove the tags )
3. Click "To Do (Ctrl+1)" again to add the Checkbox to list.

Shortcoming
But this way is flawed.
If the To Do list like follow list.  there are some NOT To Do Items among the list.

Re-Tags the list. We will find that the NOT To Do Items are all added Checkbox too. These are not what we want.
