Resizing Axis in App Designer Leaves 2nd image in GUI display

My GUI looks ok, and all the code runs ok.

But, I want to add a few more text boxes, thus I need to enlarge the size, then resize the two plots. What happens when I do this is shown below, First step is I enlarge the Rx Signal axis, then when I drag it into position, I get a a total mess where there's another image of the 2nd axis and the Tx Signal axis I haven't touched, disappears...

Hi @Dr W Kurt, it would be helpful if you could provide the .mlapp file. Then it would be easier to debug the issue since it is difficult to recreate your GUI from scratch wih just the picture provided.
