Interventions that show up multiple times (e.g. "None") seem to be causing overlap issues. For example:
- When selecting "Renal carcinoma", "Ovarian cancer" data types are visible even without a suitable model.
- When selecting "Ovarian cancer", the "None" intervention is displayed from the "Renal carcinoma" definition.
The DB schema needs an overhaul to remediate the issue, unfortunately.
