Hi John,
I'm not familar with this app or why you have it in your image in the first place (it's not a standard install on Enterprise at least from what I can see).
However, you could try the following generic method, which I use to clean up the Language Pack amongst others -
In a Powershell Administrative Window (Run As Admin) -
get-appxpackage -allusers | select name, packagefullname
Look for your ToDo app on the list (this is not alphabetical), and then mouse-over COPY just the packagefullname (on the right).
remove-appxpackage -allusers -package "<PASTE the packagefullname>"
Then Capture your image again, and see if it's fixed the issue.
