Component issue on adjacent pieces

I wanted to make a side kickplate on this cabinet model. I first created the front kickplate and made it a component. I used the rectangle tool to draw a 3/4 x 3 1/2 rectangle on the back of the front kickplate and pulled it out to the back of the cabinet to create the side piece. When I tried to make this a component and used the select tool and clicked three times it put a blue border around the side as well as the front kickplate. Hopefully, I’ve attached a picture of what I’m talking about. Is this OK or do I need to make sure the side is a separate component?

I would make each piece a component.

Probably the front kickplate was opened for edit when you drew the rectangle so the side became part of the front. Make sure the front component is closed before you start drawing the side…

Spot on! That was the problem. Thanks.
