Hidden IPv4 iBGP routes

I was troubleshooting a problem last night and it boiled down to a
Juniper router that was not a whole slew of iBGP routes from a
neighboring ASR9K. I'm too new to Junos to decipher the reason for it.
I had to disguise it a bit, so I hope it's still readable. What does
this actually mean? Can you tell from this output why it is being
hidden?
