CAF - Couldn't load the ExtendedGroupInfo tab

Hello Experts,

We are upgrading BPM from wM95 to wM10.1. Deployed the CAF pages successfully.

In MWS, while navigating to the Monitoring<Business<Tasks<specified application–by hitting a Group number from the Task Results-

In the ExtendedGroupInfo tab–getting error as “During update: jsfwmp381338:groupExtendedInfohideablePanel not found:
Error: During update: jsfwmp381338:groupExtendedInfohideablePanel not found”.

We didnt see this error before!! Please suggest what’s the root cause of it.
Thanks in advance.

Thanks,
Lavanya.
