List Field, with attribute slushbucket. "add/remove multiple" when clicked not returning the right table info

[abel91740]

We noticed that the field Recipient group which the field is a List, with attribute with shown in the picture 1 that it is not returning groups instead it is returning incident shown in picture 2

We also noticed that we are on London patch 1 and there is a lot of problem on the patch 1. 

When we compared our 3 different instances which are London Patch 1, London Patch Hotfix 4 , Jakarta Patch 10

Both London Patch Hotfix 4 , Jakarta Patch 10 are working fine, and only London Patch 1 is having an issue. 

Therefore wondering if it is the patch problem and is fixed after London Patch 1. Thank you
