Thanks for the PR @PomanoB but there's already a PR out to fix this issue: #3557

Of course, you can close this pull-request if not agree with small fix or #3557 is coming

@PomanoB please update this branch so we can review it, or close it if no longer relevant. we will close this if we do not hear from you in two weeks.
