Contour hints glitch?

I am going through the Morphing chapter in Animate Getting Started pdf.

I ran into a problem where the Contour hints I place in key drawings one and two start at “1” and the hints in key drawing three and four (the key drawing at frame 30) and starts at "0."

Is there a way to manually reset the count for the faulty key drawing or do I need to start with a new project?

Hard to know if its me or the software or my PC.
Whats the recommendation?

Your zero will be somewhere. Pan around the screen and look.

I have never had one of the numbers not appear.

It should not be possible for you to have a number in one drawing and not in another. When you create the hint on your first key drawing, at that moment that hint is also created on your second key drawing.
