Training “list” entity

Hello! Can someone explain to me how I should train a “list” entity? I did something like: { “end”: 45, “entity”: “data”, “start”: 40, “value”: “d” }, { “end”: 57, “entity”: “data”, “start”: 50, “value”: “c” }, But I’m getting this warning: Found conflicting synonym definitions for u’a’. Overwriting target ‘b’ with ‘c’. Check your training data and remove conflicting synonym definitions to prevent this from happening.

Can you upload your complete training data? The error message suggests that the problem is actually in the entity_synonyms section.

My training data is very big. And I don’t have any synonyms for this entity or for the values…
