[Resolved] Need help assigning credits and environment overwriting workflow

I have a multisite environment on WPEngine with a Main site and one Child site. I have both of these registered as the Production sites in my account.

WPEngine allows me to have a Staging and Development environment that mirrors my Production environment.

I want to know if there is a correct workflow for this situation when WPML is involved. I've copied the Production environment to the Staging environment, and things don't appear to be working correctly.

Today, I tried to remove credits from my Staging and Development environments, intending to do this before overwriting the Staging environment, hoping it would help, but now the WPML Admin says the only site with credits associated with it is the Staging Child site (see attached "Admin Credits Listing.png"). But looking at the WPML > Translation Management > Tools tab of each of the sites associated with the WPML admin, the only site with credits attributed to it is the Production Child site (see attached "marshberry.com-eu Tools Admin.png" attachment).

Am I doing something wrong? I will need to be able to overwrite the development sites on a regular basis for feature development. Is there a setting or something I'm missing?

I'm not providing debug information because I don't know which site I should provide it for.
