When I extrude the blue 3 d sketch goes invisable

I m new to 3 cad and have been learning . This problem just showed up . When I edit my drawing it looks fine. When I add a feature to the sketch then when I hit the extrude button everything goes invisable only showing faint lines . https://cad.onshape.com/documents/8c67cdbb8043b53614a185b9/w/5f8ee90585d5878061020ad1/e/8cda6c33792df8982598a443

I highly suggest going through the free beginner lessons available. No idea why all the empty sketches and repeats? Getting through the first few lessons should help to get through a simple part like this.

Attached is a sample of one way to accomplish the task. Makes it look a lot simpler. See above for more explanation.

Hope you enjoy learning On Shape. 😋
To your original question. You deleted the part instead of extruding.
