Please see which templates are using a particular global response set.
We have had a few cases where one of the following happened
- Someone used a global response set in a new template, and then the owner/creator changed the list because they needed to update it for their templates, and it no longer worked in the new templates
- The owner/creator added a response to a global response set that did not make sense for all the templates they were using it in
- We had a request to change a global response set, and we are not sure if we can because we don’t know what forms use it
