Bug Description

I came across a bug that seems very specific to one filing accession number.

When I try to get a Part II item using get_item_with_part, it returns None for this accession number:

company = Company('915358') 
filings = company.get_filings(accession_number='0000915358-25-000018') 
filing = filings[0] 
data_obj = filing.obj() 
data_obj.get_item_with_part('Part II', 'Item 7', markdown=False)

However, the same data can be accessed correctly if I fetch the item directly:
data_obj.__getitem__('Item 7') or data_obj.management_discussion

Expected behavior:
get_item_with_part('Part II', 'Item 7') should return the same result as data_obj.getitem('Item 7').
