Hello ,

We use key flexfield ,of type - people group. 
We are trying to have a different label instead of ‘people group ‘ for the kff in the pages. Also a different label when legal employer is IL or another. 
I first tried by the kff setup - in the regular translation - in Hebrew and English for the kff label ,and generated the kff. - it didn’t work ,the label remained the same. 

Then tried to change the label by personalization using ‘page composer’ sandbox. When navigating into the page - structure - to ‘kff ‘
