How to turn off project mirroring from SourcForge to launchpad?

I have project [Emle][1] in [Launchpad][2]. I set it to import from [emle.svn.sourceforge.net][3]. My intention was to do a single import of the files from SourceForge.

[Emle>Branches>2.0][4] shows that what I actually did was set it to mirror the SourceForge project.

    Import details
    Import Status: Reviewed
    This branch is an import of the Subversion branch from https://emle.svn.sourceforge.net/svnroot/emle/trunk.

    The next import is scheduled to run in 35 minutes.
    Last successful import was 5 hours ago.

     Import started 5 hours ago on russkaya and finished 5 hours ago taking 30 seconds — see the log

How can I turn off the mirroring?
