When enabling k8s filters ui.k8s_enabled=true the filters drop-down was working as expected (i.e. you select k8s all from the list and in the textbox you get the respective gremlin query), but when doing the same with the highlight drop-down the label k8s all was present in the highlight text box while the value in the filters textbox would change and display the gremlin representation (of what was selected via the highlight drop-down).
this PR fixes the bug
