Hello Stephen, thank you for responding to my post so quickly.
Sadly, that is what I have been doing, but I haven't had any luck. When I try updating the workflow using the method you mentioned, it disappears from my list for about 10 minutes and then shows up again, still requesting an update.
I tried deleting the old version and redownloading the newly updated workflow from the Gallery, but now I can't even delete the old workflow. When I try going into the alfredpreferences.app in my folders to delete it manually, I get the error message attached.
