Post From: New Instance, Different Data

I'm doing some back testing and I've opened a New Instance on two operating SC main instances.

This gives me the opportunity to run four back tests at the same time.

The problem I'm having is that one of the New Instances is not reporting the same data as the other three. I'm running one chart - NQU23-CME. Three of the charts are reporting the same data for my starting point of 2023-07-05, the other is reporting something very different.
Three of them open this day with a price of (roughly) 15292 while this fourth is showing an opening price on that day, at 9:30 eastern, of 15410.
All of these charts are the same. I copied the chart book from one to another. They are all using Continuous Contract, Date Rule Rollover, Back Adjusted data. They are all operating in the same contract period (the current contract).
It is my understanding the SubInstance gets its data from the main instance so I cannot understand why I'm seeing this.
Can you offer any suggestions?
