Hi @ajnunezjr ,
Does this have an impact on your further configuration of Flow, and if so, please give us feedback.
I did the test using the same template, and a similar issue appeared, as below:
You could try to switch the environment to default and then click on "Edit in advanced mode" to use this template.
I am unable to find out why other environments cannot use this template currently, this template can be used in the default environment.
Please take a try.
Best Regards,
