Project PWA JS Grid – How to filter reference table values displayed in dropdown multivalue control

  javascript, project, sharepoint

I’ve really been stuck on this for a long time. I’m not able to filter the values ​​of a reference table, values ​​that are displayed in a multivalue dropdown control in a JSGrid column, in a project detail page.
What I simply need is that as per a keyword included in the Description – contains("INACTIVE") these records will be removed from the control (not from the reference table). I will try to attach an image of the control with the records I need to filter.
Any help is most welcome.
