In campaign 36's overview page at https://tools.wmflabs.org/isa/campaigns/36, not all contributors show up.
Steps to Reproduce:
Compare https://tools.wmflabs.org/isa/campaigns/36 with the csv export generated from https://tools.wmflabs.org/isa/campaigns/36/stats - that csv export also shows contributions by User:1ucyp (who told me they had contributed but their edits didn't show up).
