[Bug] Unreal Editor Linux, Can't Add Service to Behavior Tree Selector Node.

This is not working in Unreal Editor version 4.20.2 - Linux.

When I right click on a Behavior Tree Selector Node to “add service” the context menu disappears and I can’t choose any options from the “add service” sub menu. The “add decorator” sub menu works fine.

Is there an alternative way to add a service to a Selector Node?
