On-Screen HUD showing incorrect Flow value

SUMMARY
***
Selecting a Flow value in the Quick Settings Docker will not be reflected in
the On-Canvas Brush Editor HUD. Only zero (0) or one (1.00) value will be shown
in the HUD.
***


STEPS TO REPRODUCE
1. Bring up the Quick Settings Docker and switch to the Flow tab.
2. Right click on the canvas to bring up the On-Canvas Brush Editor HUD.
3. Show the brush parameter popup (or whatever it is called within the HUD) by
clicking on the right pointing arrow. This popup will show and allow you to set
various brush values, eg opacity, size, flow, etc for the selected brush.
4. Edit this popup so that the Brush Flow parameter will be shown, if not
visible.
5. Make sure both the Quick Settings Docker and the On-Canvas Brush Editor HUD
is visible at the same time and in the Quick Settings Docker click on a Flow
percentage. The selected Flow value will not be reflected in the On-Canvas
Brush Editor HUD Flow field. If you select 0.1 - 40% Flow value in the Quick
Settings Docker, the Flow value in the HUD will be zero. If you select 50 -
100% Flow value in the Quick Settings Docker, the flow value in the HUD will be
1.00.

OBSERVED RESULT
If you select 0.1 - 40% Flow value in the Quick Settings Docker, the Flow value
in the HUD will be zero. If you select 50 - 100% Flow value in the Quick
Settings Docker, the flow value in the HUD will be 1.00.


EXPECTED RESULT
The Quick Settings Docker displays percentages, but the On-Canvas Brush Editor
HUD displays float values. Possibly some conversion issue, but the On-Canvas
Brush Editor HUD should display the correct float value for the Flow that
corresponds to the percentage value selected in the Quick Settings Docker.

In the attached screenshot, 40% Flow value is selected in the Quick Settings
Docker, yet 0.00 Flow value is showing in the On-Canvas Brush Editor HUD.
