This is a regression tested in //UE4/Release-4.27 cl 18319896
Instanced Editable Variables of type Blueprint Interface can't be set.
BP_Triggerable appears and is selectable in the drop down menu. (from the ticket: "The dropdown list that should contain all blueprints that implement the Triggerable interface is empty and you can't set the Triggerable variable.")
The drop down menu is blank.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-153088 in the post.
