Analysis for Office reports header prompts are showing values as #NA in scheduled report.

Working on AO 2.8.1 Version.

After upgradation of AO version to 2.8.1, Scheduled AFO reports headers, started giving value as #NA.

Tried to remove @ from report header formulas still issue remains same.

Anyone experienced similar issue with AO 2.8.1 version?

Thank you!
