Alpine and Debian Show Different Behavior for list field __contains Query

[zjqzero]

Alpine Linux 3.21, Python 3.13.2

>>> SectorMapping.objects(sub_concepts__contains='test')._query
{'sub_concepts': 'test'}

Debian GNU/Linux 12, Python 3.13.2

>>> SectorMapping.objects(sub_concepts__contains='test')._query
{'sub_concepts': re.compile('test')}

Why do the two different systems behave inconsistently? Is it due to missing library support?
