Strange parser error: search_dates parses "2010 Year" to a date with year of 4033

Very strange issue.

dateparser.__version__
'1.1.8'


settings= {
 'RELATIVE_BASE': datetime.datetime(2023, 7, 31, 0, 0),
 'PREFER_DAY_OF_MONTH': 'first',
 'PREFER_DATES_FROM': 'future',
 'REQUIRE_PARTS': ['year', 'month'],
 'DATE_ORDER': 'YMD'
}
s = 'Closing Yield, 2010 Year Treasury notes On Dec 31, 2023'
search_dates(s, settings=settings)

Result:
Out[27]:

[('2010 Year', datetime.datetime(4033, 7, 31, 0, 0)),
 ('On Dec 31, 2023', datetime.datetime(2023, 12, 31, 0, 0))]

(impossible year 4033 from the first part of the parse)

Also, put this question on SO *link:**

Start by reproducing the reported search_dates call with the provided RELATIVE_BASE, PREFER_DATES_FROM, REQUIRE_PARTS, and DATE_ORDER settings. Trace how the parser handles the "2010 Year" fragment; done means it no longer produces the impossible year 4033 while still returning the Dec 31, 2023 result.
