When you see a duplicate listing, you can go ahead and submit an issue -> Click Edit Role -> Make sure to check the box for 'Yes, remove this internship'.

This listing is an inactive listing from 2013.

@AlmondCroffle the issue is the dataset is bad with duplicate IDs, which can be problematic for consuming projects (e.g. goodfirstjob.com/new-grad-jobs). I opened #1590 to remove the listing.
