The ghost mod only sets the listed stat at a minimum of 10, and does not guarantee it will be the highest stat.
Only the first roll might be a bug but you would need to provide video evidence for Bungie to investigate. All modern video game platforms have built-in capabilities to record the last 30 seconds or more of gameplay, either with a controller button or using the Xbox Game Bar.
Doesn't explain near identical rolls which is my main concern. I'll let Bungie decide as they hold the cards and have final say but thank you for your input
