Incorrect Evaluation Metrics Produced

`def beir_evaluation():

actual_contexts_dict = {'0': 
                           {'0': 1, '1': 1, '2': 1, '3': 1, '4': 1, '5': 1, '6': 1, '7': 1, '8': 1, '9': 1}
                        }

                   {'0': 1, '1': 1, '2': 1, '3': 1, '4': 1, '5': 1, '6': 1, '7': 1, '8': 1, '9': 1}
                }

# Evaluate retrieval metrics
ndcg, map_score, recall, precision = EvaluateRetrieval.evaluate(
    actual_contexts_dict, results_dict, k_values=[10]
)
mrr = EvaluateRetrieval.evaluate_custom(actual_contexts_dict, results_dict, [10], metric="mrr")

# Print evaluation results
print(f"\nRecall@10   : {recall['Recall@10']:.2f}")
print(f"Precision@10: {precision['P@10']:.2f}")
print(f"\nNDCG@10     : {ndcg['NDCG@10']:.2f}")
print(f"MAP@10      : {map_score['MAP@10']:.2f}")
print(f"MRR@10      : {mrr['MRR@10']:.2f}")`

Recall@10 : 0.90 Precision@10: 0.90

NDCG@10 : 0.94 MAP@10 : 0.90 MRR@10 : 1.00

This is clearly incorrect as everything should be 1. Please can this be resolved

# Run the evaluation
beir_evaluation()

Recall@10 : 1.00 Precision@10: 0.95

NDCG@10 : 1.00 MAP@10 : 1.00 MRR@10 : 1.00

Why is precision@10 not 1.00 ?
