Cloud Print: Label Template Fix
To fix the issue you will need to go into Mobile Label Templates
Then select the label that is causing the issue and delete it.
Then select the "Create Default Templates", that will remake the label with the correct template path.
You can test this by select the label and then chose the "Open In Designer" action that will open Interform and show the label template there if the path is correct*.
*This can only be done if the customer is on a custom print tenant.
