Multiple value seperator in saml Attribute

Hello All,

Issue: 
I need to figure out how to seperate multiple values to be sent as a saml attribute.  One of the values is based off of a value that the user is a member of in AD that is capture in my custom variable assign and the other is going to be statically assigned. 

When I try above which matches what I read to do, saml trace still shows pipes instead of having each group on its own attrbute line.

What I have tried:

I have tried to follow this acticle and use pipes but it is not working.  https://support.f5.com/csp/article/K50421104

Other information:
running version 16.1.2.1

thank you for your help!
