Bug fix for bulk add feature

When adding posts in bulk, only the first section is picked up.

In practice, for example, I add 4 posts to the roadmap as admin, using the location to add several at once. And even though I selected the functionality to go to a specific section of the roadmap, it appears as if I had not selected any section within the roadmap. (then requires the admin to go in one by one to correct it and put it in the place it should have been when it was registered.)
