The first screenshot shows how I reached this point. The second screenshot displays two rectangles — one with a green border and the other with a red border.
Before I began creating my custom controls, the IDE only showed the green-bordered ancestor component. After developing several custom components, I noticed that the red-bordered rectangle components started appearing as well.
My question:
How can I revert things so that only the single green-bordered TCustomControl ancestor rectangle is displayed again, and remove the additional red-bordered design-time outlines? Or is this normal and expected behavior?
