Team Support on CLI

We have deployed an IOS app to testflight. The builds were generally done by one person (for 38 builds) but the last was done by another team member. However, it seems that the document directory on the app is unique to the team member that built the ipa. So when an user updates the app, they lose their data living on their document directory. We have the following two directories on the device after the upgrade.
I can’t see where FileSystem is creating the directory with the experienceID, but I’m wondering if I am understanding the behavior correctly or if there is a work around so any team member can build the app and expect the upgrade to work properly.
