TAdvGlowButton Down-State does hover once

I use a TAdvGlowButton and want to use the Down state.

I set (either during runtime or in the designer) the following attributes:
GroupIndex=1, Down=true and Font=bold

This is working, but the button does the hover-coloring when hovering over the button.
As soon as I click the button, the hovering does not happen anymore.

I would expect no hovering at all.

Is there a way to avoid the first time hover effect?

Tested on C++Builder Tokyo and TMS 13.5.13.0

Thanks
