Abilities with hotkeys appear in the middle of the screen

In an earlier post I put the mouse over my monk ability and pressed the "print screen" key to make a screenshot.

Since then the icon of the ability is in the center of the screen, near the position of the "game paused" writing. This is the left part of the image.

When I press the button again while the mouse is over this ability, the ability does not use this hotkey anymore and the center of the screen looks like the right part of the image.

 

Edit:

Looks like the icon on the right side disappears after some time.

I do not know how to remove the icons on the left side.
