Repeated output with apt-cache show

When I run
apt-cache show nginx
I get

but it's printed twice. The same happens with apt-cache show firefox.

Other ones work fine: apt-cache show with geany or gedit or medit or google-chrome-stable give the data just once (as expected).

Does anyone else see the same?

This is on 13.10.

Just tested with firefox, yes, it outputs twice ..
Edit1 :

Code:

dpkg --print-avail firefox

has only one output.
Edit2 : http://lists.debian.org/deity/2001/04/msg00038.html. Old thread but Matt Zimmerman says : "Note that both erlang and erlang-base appear twice (apparently because they exist both in non-US and in the main archive)" so I guess it could be normal

How many are listed when you run
apt-cache policy "package" ?

Don't quite know what to say but it's nice that it's not just me

Yes, in the present case, they're in saucy-updates and in saucy-security.

I thought I had messed up something because I'm learning a bit about Bash and maybe some command I entered did something weird when I wasn't looking

Eheh, I do not think you have messed up anything, or we have both
