All brokerage accounts double as Cash and Security are same
Each Brokerage account has a balance is double what it should be due to the addition of a non-existent cash balance for the same amount as my investments.
This occurred after the installation of R47.15 Build 27.1.47.15
It creates a XLN or Xout in each case causing the error.
When reloading the account from scratch, it no longer asks for cash balance, which fixed the issue in prior releases.
