Command Bar - Navigation - Group name is not being changed

Hi,

On a Contact form, I have some related entities link on command bar. I want to change heading (Group Name )to "Housing".

I tried changing it from "Procession Session" to housing but from Form navigation Group Name but still it shows "Process Session". Also I cleared browser caching but no luck.

I am using CRM2016 Update2 - On Premises. 

Any suggestion please?

Thanks & Regards,

Chirag
