Not detecting date when adding words to date string

Hi,
I am testing dateparser and it seems that it may not work in some cases if the string containing the date contains additional words.

In the following example, I added the term "fr" to the string (randomly chosen), and tested DateDataParser in Spanish and English. While the latter worked, the former did not.

Spanish

IN

dt = "fr 18 Mayo 2021"
ddp = DateDataParser(languages=['es'])
ddp.get_date_data(dt, date_formats=["fr %d %B %Y"])

OUT

DateData(date_obj=None, period='day', locale=None)

English

IN

dt = "fr 18 May 2021"
ddp = DateDataParser(languages=['en'])
ddp.get_date_data(dt, date_formats=["fr %d %B %Y"])

OUT

DateData(date_obj=datetime.datetime(2021, 5, 18, 0, 0), period='day', locale=None)

Any thoughts on this? I am using v1.0.0

UPDATE

After searching a bit more I realised that you state

The input string it's a valid date and it doesn't contain any other words or numbers.

I understand this if no format is given. However, if a format is given, where the added word is included (like in the example), perhaps it should work?

For now I'll be using:

from datetime import datetime
import locale

locale.setlocale(locale.LC_TIME, "es_ES")
dt = "fr 18 Mayo 2021"
datetime.strptime(dt, "fr %d %B %Y")

Start with the DateDataParser.get_date_data reproducer using Spanish and the format "fr %d %B %Y", then compare it with the working English example. Trace how the supplied date format and Spanish month name are handled; done means the Spanish input returns the expected 18 May 2021 date.
