Voiceover braille screen input practice does not work

1. Open Voiceover settings,
2. Double tap the Voiceover practice option,
Here, you are able to perform gestures and hear their descriptions. You will notice two tabs at the top, general and braille.
Double tap the braille tab to make sure it is selected.
Try performing a gesture such as swiping right, swiping right with two fingers, or another gesture available in the braille screen input mode.
You will notice that VoiceOver incorrectly still gives descriptions for the standard operations of each gesture.
For example, swiping right says that it will move to the next item, while when the braille tab is active, it should instead announce that the gesture performs a space.
