This bug was introduced in the commit made on September 1, 2019 that attempted to fix issue #521: Recursive call overrides earlier data

Confirmed that the cause of problem in issue #554 is due to fix for issue #521. Will disable "fix" for issue #521 till get proper "fix" for issue #521, since issue #554 addresses behavior that is more fundamental.
