Hamburger menu not showing

I have a student who is putting a Mobiscroll calendar on a form (we’ve done this a lot). He is having trouble with the sizing of the calendar so it is about half the form height and scrolls so the hamburger menu created on the first form shows on the calendar page and all the other pages but not on the login page. The hamburger hidden property is set to true in the design. Then in the app, on the calendar form .onshow event the hamburger hidden property is changed to false.
Using Apopstudio 9.4.7.1 on a Mac.
Note: it does work (log in, then shows the calendar with data from remote database) with no console errors.

Thoughts?
