Turning off markup tools on an iPhone

I rarely use the markup tools at the bottom of the screen when I annotate photos. I almost always add shapes and texts. Normally, I can tap on the screen and get a 'select all' option and then copy all the shapes and texts to paste in other phots. However, when the markup tools accidentally get tapped, I cannot turn them off! When I tap the screen I either get dots from whatever tool got turned on or a blank circle for the eraser. Sometimes—days later—the tools will turn off and I'm back in business. I just cannot find a way to do this directly. I have tried power-cycling the phone, but that hasn't helped. I tried resetting the phone and then created major headaches.
