slackbuilds rsync have uncompressed packages

I'm sorry if my question is obvious
After some problems with the updates of my system with Sbopkg and Slpkg, I think it had some old packages, which had changed, and they were no longer in the repository or are now in the Slackware packages. After some scripts to find these unattended packages, I have noticed that my RSYNC Slackbuilds repository has some uncompressed packages like QtiPlot.
With the objective of the aid, I have signed to the Slackbuilds list after sent them an email, but I do not know if they will answer me because I publish not a member to a list of only members and I am curious to know the reason are these packages there.

To find that uncompressed packages i grep on files that only have 2 match tar.gz and tzr.gz.asc and don't have an extracted dir or SlackBuilds or .ifo ... maybe some checks are wrong, i only check a few for now and there are old versions.
