up2date package in two current-db : different behaviour???

Hello everyone,

	I'm going crazy here :)... I don't know why this is happening:

RedHat release up2date-2.7.46 some time ago and then followed with
up2date-2.7.61 some time later.

I have two channels: redhat-6.2-sparc and redhat-7.2-i386..

On the same current server (rpm-4.0.4, python-2.2 and current-1.02), I get
this when rebuildind the databases...

RH7.2 (example with up2date-gnome but the same happens on "up2date"
itself):

Apr %2m 10:53:37 Adding up2date-gnome-2.7.11-7.x.2.i386.rpm
pkg0 = up2date-gnome, pkg4 = i386, filename = up2date-gnome-2.7.11-7.x.2.i386.rpm
Apr %2m 10:54:03 Removing up2date-gnome-2.7.11-7.x.2.i386.rpm
Apr %2m 10:54:04 Adding up2date-gnome-2.7.46-7.x.2.i386.rpm
pkg0 = up2date-gnome, pkg4 = i386, filename = up2date-gnome-2.7.46-7.x.2.i386.rpm
Apr %2m 10:54:23 Removing up2date-gnome-2.7.46-7.x.2.i386.rpm
Apr %2m 10:54:24 Adding up2date-gnome-2.7.61-7.x.2.i386.rpm

So the latest package is: 2.7.61

But on RH6.2 sparc, I get this:

Apr %2m 10:55:03 Adding up2date-gnome-2.7.11-6.x.1.sparc.rpm
pkg0 = up2date-gnome, pkg4 = sparc, filename = up2date-gnome-2.7.11-6.x.1.sparc.rpm
Apr %2m 10:55:03 Removing up2date-gnome-2.7.11-6.x.1.sparc.rpm
Apr %2m 10:55:03 Adding up2date-gnome-2.7.61-6.x.1.sparc.rpm
pkg0 = up2date-gnome, pkg4 = sparc, filename = up2date-gnome-2.7.61-6.x.1.sparc.rpm
Apr %2m 10:55:09 Removing up2date-gnome-2.7.61-6.x.1.sparc.rpm
Apr %2m 10:55:10 Adding up2date-gnome-2.7.46-6.x.1.sparc.rpm

So it finds that the latest version is 2.7.46???

Here are the files I have:

Do anyone know what's going on and where I should start investigating..?
