Blank screen when using custom databse in Model-Targets sample app

I've successfully gotten the Model-Targets app to run, but when I import the .xml and .dat files from any device databases that I create through the portal, the sample app shows a black background behind the "Reset" button. There is no helpful messaging in the logs.

I am evaluating Vuforia for a client and really need to get past this initial step and this is time sensitive. Any help would be greatly appreciated.

Steps:

1. Scan any object with the scanner
2. Test the scan in the scanner app to verify it scanned correctly
3. Share the .od file to Google Drive
4. Download the .od file from Google Drive to my local machine
5. Create a new device database
6. "Add a Target" to the database by selecting the downloaded .od file
7. Wait until status shows "active" on the target
8. Download the database for Android (in .zip format)
9. Unzip the database 
10. Copy .xml and .dat files into the asset folder in the sample app
11. Change the path in the mDataset.load(...) call to the name of my new .xml file which is in /assets along side VuforiaMars_ModelTarget.xml
12. Run the app

Enviroments:

• Scanner 1.0
• Vuforia 7.1.34
• Scanner and sample app are running on a Pixel 2 w/ Android 8.1.0

Attached is one of the 3 databases I have tried.
