Missing Material Functions in Blueprint After Migration

I’m having a problem when attempting to migrate one of my material blueprints between projects. When opening the material editor in the new project, a few of my material function nodes went missing; Specifically, “MF_BaseColorTintandContrast”. Below I have screenshots from the nodes in the original project, followed by the missing nodes after migrating.


Both projects are in UE5; The first was created in early access and the second in the full release, but the function still appears in the original project when opened in the full release version. This is a crucial node that my material can’t function without, and a crucial material that I use for post processing on several projects. Could anyone please help me find a way to recover these nodes or replace them somehow?

Thanks in advance!
