One common practice people miss is setting the wrong animation priority. Make sure your animations’ priorities are set to Action. This priority level will have it play over any other animations (e.g. idle, walking, and jumping).
Also, make sure there are no other factors at play here. Like Battle said, If you didn’t already switch the animation IDs over to the new ones that have been created in the group then do that. Make sure you are playing the animations too.
Here is where you can change the priority via the Animation Editor plugin:
