Android.ProgressIndicator has unexpected consequence when app is resumed after closed in background

I have a progress indicator that I have on my navigation page that is shown any time a user clicks on a button. The progress indicator is hidden once all loading is done. It works as expected with no problems, unless the user clicks the 'home' button and the OS closes the app in the background. When the user resumes the app it restarts (going through the splash screen), but there is a translucent screen covering everything and I can't click anything underneath it. Pressing the 'back' button on the phone closes it, but it also closes the window underneath that. This only happens if the progress indicator is shown at least once and the app is closed in the background. In every other scenario there is no translucent window.

Here is how I declare my progress indicator:

var navPageprogressIndicator = Ti.UI.Android.createProgressIndicator({
              message: 'Loading...',
              location: Ti.UI.Android.PROGRESS_INDICATOR_DIALOG,
              type: Ti.UI.Android.PROGRESS_INDICATOR_INDETERMINANT,
              cancelable: true
            });

I've tried using modal:true/false on windows with no difference and I've tried setting cancelable to false, but neither make a difference.
