These seem to have been created quite a few years ago before the {{Top Level}} was in wide use. I have added it to the category, but since it contains 47 profiles, they will all end up in the suggestions list.
It does appear that the category was created by or in coordination with the WW Disasters project in order to group people who died during the pandemic.
EDIT: Top level is cleared of all but one profile, which will be moved out once it is opened.
