[Spacewalk-list] some channel is not showing under manage software channel

[YANG LI]

I have a strange issue. I created a channel, It was working fine until this morning. I can see it from software channels - All Channels under web ui, but I can not see it from manage software channels any more. only thing I did last night was to sync all channels. this is what I see from output of the sync regarding that channel. 

/usr/bin/spacewalk-repo-sync -t yum -c sles11-sp3-updates-novel -u https://xxxxxx:xxxxxxx@nu.novell.com/repo/$RCE/SLES11-SP3-Updates/sle-11-x86_64/
