Are you doing this and Gnuton testing? I am a little worried what they produce may be different to your builds? Yours are easy to flash to and flash back to stock if required and work with many plugins.The GT-BE98 cannot be sold in North America for regulatory reasons, any shipped device sample might get rejected at the border. That's why Gnuton is taking care of it since he lives in Europe.
First screenshot.
Do the builds sit in your onedrive area when testing and same place as usual when released?
