Potential Bug with App Designed to Create Subplots of Polar Axes?

I am trying to programmatically generate a set of polar subplots in my Matlab application. It seems to work almost perfectly, but when I generate polar axis subplots in my app, an empty figure window is generated at the first subplot call (and none of the others). I thought I had left a 'figure' command in my code somewhere, but that is not the problem. I have included a minimally functional reproduction of the problem in the pasted code below (this site won't allow me to attach a file with the .mlapp extension). I tried adding a breakpoint at the first 'ax1 = subplot(2...' call and then stepping into the subplot function, but the figure window pops up as soon as the debugger jumps into that function. I am at a loss and want to know if I have messed something up, or if this is a bug that needs fixing.
The example application below contains one button, whose callback function generates the subplots.
Please let me know if you need more details to answer this question.
