Timer OnTimerEnd Not Working on First Run

[RABronn]

I have a timer that navigates to a different screen OnTimerEnd. The timer runs when the screen loads, but when the timer ends, nothing happens. However, if I press the timer again it runs and navigates as it should. 

It did work once, but then I deleted a screen (a test screen with a different timer that had not worked - it was not referenced by the timer that worked in any way), and I could not get it to work again, so I kept trying different settings and now I'm on Version 46 with no luck.

How do I get the timer to work correctly the first time, or rerun a second time to trigger the navigation?
