After investigation, it seems that the we have attack patterns with the same name and same kill chain phase in the database (but different ids and different data). They shouldn't have the same kill chain phase, I don't know if it's an ingestion issue, or if we manipulated them in our platforms. There are no issues with the matrix view.
