Animate CC 2020 shape hints don't have markers

I recently installed Animate CC 2020 and I tried adding shape hints to a circle so I approrpriately can morph it into a square, but the shape hints don't have the usual alphabetical markers. This makes it hard for me to know what order I've created the shape hints in (I can't tell which one's "a" or "b", etc.). See the screenshot for reference:

Does anyone have any clue how I can turn on the shape hint markers? I'm using Animate on MacOS Catalina.
