Encountered bug while testing batching sizes.

• Spacy model: French
• Batching size: 4
• Debugging NER output: [{'entity_group': 'MISC', 'score': np.float32(0.9299379), 'word': 'ESZ', 'start': 41, 'end': 44}, {'entity_group': 'PER', 'score': np.float32(0.98025304), 'word': 'lino.silva1', 'start': 49, 'end': 60}, {'entity_group': 'PER', 'score': np.float32(0.9931357), 'word': '', 'start': 140, 'end': 141}]
• File: Re reunião agendada para o dia 24 de abril 2024-04-17T17_39_49+02 00.eml

Also occurs in test email 250

• Spacy model: French
• Batching size: -1
• Debugging NER output: {'entity_group': 'ORG', 'score': np.float32(0.8815035), 'word': '', 'start': 1749, 'end': 1750}

Issue only seems to occur for large batching sizes, batch size 1 has worked for both emails. Issue is not related to spacy model language, since this email is in french.
