How to change the node description in property Tree

Hi Experts,

I need to update the “Food/Paper Regulations”(Selected one) property node to “Other EU Food/Paper Regulations”.  And remove the “GRAS” property.

Class Name of “Food/Paper Regulations” is ZAP_EHS_1024_126

I opened CL02 for this class and change the description-

But still if I go back to CG02 and see the description then it’s same not updated-

Can someone please suggest why its not updating here?

And how can we delete the GRAS node.Its only to remove the value assignment type from below screen or something else to do-

Please suggest me on this also..Thanks in advance.

Regards
