Tried to delete a dataset ("Geospatial" with no files in it) and even refreshed the page a few time but the dataset it still there. This happened in sead2.ncsa, in the Open Testing space, on the "Must Have" collection page: https://sead2.ncsa.illinois.edu/collection/56cca57ee4b0c3d1897ef489.

The pop-up message does show up asking to confirm the delete action, I say yes, but, again, the dataset stays on the page.
