Clicking and dragging on an aircraft tag with both mouse buttons make the tag disappear

After accidentally pressing by mistake on an aircraft tag in the lower-right ATC section with both mouse buttons, I dragged the mouse, and when I released the buttons, the tag disappeared, and the tag that is shown on the screen for an aircraft gets stuck.

As can be seen in the screenshot, all the aircraft available at the beginning of the level have all been deleted this way, and all the tags got stuck at the center of the screen.
