I have a solution for this, but, I'll need some information. Could you please export the .aia file of your program and post it here?
Steps to export your project's .aia:
Step 1: Open and sign onto App Inventor.
Step 2: Open the app whose .aia you want to export.
Step 3: Click on the My Projects drop-down menu located near the top of the page, and click on "export selected project (.aia) to my computer" in it.
You can use the upload function on this community (picture below for reference) to upload a file onto it:
