These are packages installed from the VL repositories. I just double checked mine and everything i see there are from what i pulled in from our repos. Don't feel bad, I broke vector many times in the beginning, Just stay with those 3 repositories for now until you become more comfortable.
I think there are some packages listed there that I created with vpackager, but yes, most seem to be from the repos.
I always uncheck testing when I'm done and update gslapt again, this way your back to your 3 main repositories.
This is what I normally do, but I believe I screwed up one time and mistakenly updated before returning the repos to the three main repositories, and I believe this is messing up some of the aforementioned programs.
... Unprecedented to any Linux distribution i have ever used. 
I agree. It is great.
I'm hoping to undo the damage I did with the accidental upgrade, and I think that the reservoir of packages in /home/ftp/pub is holding Gslapt back from downgrading them -- IE, it won't downgrade if it has access to a higher source, which in this case is the local source of /home/ftp/pub. So, along with keeping the listed sources in Gslapt as stable, I'm also going to remove the packages from here, and then go through the list of packages that were there and reinstall them. If I'm right, since the local source of possible testing and/or unstable packages that I accidentally installed is gone, then some of the packages will have to be downgraded, thus returning me to stable. Unfortunately this will break a few of the Slackware programs that I put on that required some newer packages, but I can always tend to those later.
Of course, I may be way off here and break the entire system. Oh well, it'll teach me to always be careful about sources before upgrading. The developers really should put in something like the Debian Preferences option to allow for greater control of users in having a mixed system.
Thanks for your great help. I'll report back on how my efforts went.
