That's odd considering you don't have any filters applied to the interfaces. Do you have any configuration groups? Can you post the output of:
(R4)
show interfaces ge-0/0/0
show configuration interfaces ge-0/0/0 | display inheritance
show configuration interfaces lo0.0 | display inheritance
(R2)
show interfaces ge-0/0/1
show configuration interfaces ge-0/0/1 | display inheritance
show configuration interfaces lo0.0 | display inheritance
