Has anyone experienced this issue before?
Report Builder works fine for me in other Excel workbooks, but certain files shows this when I go to 'Manage' option of Report Builder.
I'm running version 126.96.36.199 currently which I believe is up to date.
It appears this may have been a bug with either Excel or Report Builder. If you continue to experience this issue, please open a ticket with Customer Care so they can replicate the bug and log it for our engineering team.
