Pupils not Recognizing Eyeball and Pupil Range

This is the first time encountering this error and don't know how to fix it. These were the errors:

Left Eyeball Layer tagger as Left Pupil Range is not being used by any behaviors

Right Eyeball Layer tagger as Right Pupil Range is not being used by any behaviors

The eyeball layers were recognized by the program but not been applied to the puppet but follows the default eyeshape. Any help would be greatly appreciated.
