Problem "Could not find month"

I am getting the following error messages. They seem to stop Hazel from working of many minutes. The folder I am processing has hundreds of rules so I am unable to determine which rule is causing the problem. Here are some of the errors:
024-04-22 19:31:51.156 hazelworker[11917] Could not find month: Aout
2024-04-22 19:36:38.763 hazelworker[11917] Could not find month: fevrier
2024-04-22 19:40:46.468 hazelworker[11917] Could not find month: Aout

2024-04-22 19:52:00.918 hazelworker[13075] Could not find month: fevrier
2024-04-22 19:55:54.238 hazelworker[13075] Could not find month: Aout
2024-04-22 19:56:53.348 hazelworker[13075] Could not find month: fevrier
2024-04-22 20:01:21.598 hazelworker[13075] Could not find month: decembre
2024-04-22 20:11:34.227 hazelworker[13075] Could not find month: decembre
It's worth noticing that these are the only months in french which normally have accents. They are normally février, aoüt, and décembre.
I can't find any files without the accent on the french dates, and the accented ones seem to correctly interpret as Feb, Aug and Dec (in English)
I have literally hundreds of rules pertaining to this folder, and each rule looks for a date - autometically detecting the date.
Any ideas why this is blocking Hazel?
