Continue button not working

I have created several courses (what we are calling modules) for a course. There are no requirements for the learner to move forward so I have left all of the continue buttons set to "None Always show button." I have not changed it for any of the lessons. I have 3 lessons' CONTINUE button inside one module that are not acting as expected. Usually they just bounce the learner into the next lesson. These are adding a step. See attached picture for reference. Any ideas? I have already deleted them, logged all the way out, cleared cache, and reset to no avail. Thanks so much!!
