If DCI has node name in "Template" column this means that this DCI was created by instance discovery. Somewhere on the node there should be prototype DCI, which defines how instance discovery is happening.
e.g. in the attache image DCI with ID 4957 is instance prototype. It's coming from Generic UNIX template. Other DCI are created with instance discovery based on this DCI.
