Change the translations export branch

While setting up the translations for my project https://launchpad.net/issuetrackertracker, I tried to put
    lp:issuetrackertracker
as the branch to which export the .po files. However, this was not recognized, so I wanted to add
    lp:~itt-devs/issuetrackertracker/main
which is the same branch as lp:issuetrackertracker.

In order to add this branch, I put "main" in the search box. It returned one branch:
    lp:~emilien-klein/issuetrackertracker/main
which is the original development branch that I don't use anymore.

It was my mistake to not have seen that the wrong branch got returned from the search, but now the export has been done to the wrong branch. Now I am trying to change the branch, but if I enter "~itt-devs/issuetrackertracker/main" I always get an error message.

Could someone change the export branch for trunk to point to lp:issuetrackertracker, i.e. lp:~itt-devs/issuetrackertracker/main?

Thanks,
Emilien.
