Custom Primitive Data values don't stick when editing them in the detail panel on a placed BP actor containing a Static Mesh Component.
Create a BP actor with a Static Mesh component with one Custom Primitive Data entry
Add the BP to the scene
Change the Custom Primitive Data (output the custom primitive data as color in a material to view)
See how the value is retained in the detail panel, but the read value in the material is reset to 0 after editing it.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-173061 in the post.
