I just checked the feature_spec.yml file in the model registry and realized my feature tables are not tracked but only the final dataset. 

input_columns:
- user_id:
    data_type: int
    topological_ordering: 2
    source: training_data
- item_id:
    data_type: int
    topological_ordering: 0
    source: training_data
- timestamp:
    data_type: timestamp
    topological_ordering: 1
    source: training_data
workspace_id: '329425024234434367'
feature_store_client_version: 0.14.3
