Issue with overwrite field

[ASHLYNZ]

I'm having issue with overwrite field of extracting data from Bloomberg by setting currency to CAD

# import pandas as pd
#import pdblp
#hp_base = pd.DataFrame(con.bdh(SecList, Fields,business_day_month,end_date,ovrds=[('Currency','CAD')]))
#hp_local = pd.DataFrame(con.bdh(SecList, Fields,business_day_month,end_date]))

Expected Output

hoping to see hp_base in Canadian dollar while hp_local return the security in local currency.
###Actual output
the 2 output are identical. both returned local currency. There is no issue with run hp_base:

hp_base = pd.DataFrame(con.bdh(SecList, Fields,business_day_month,end_date,ovrds=[('Currency','CAD')]))

overrides[] = {
overrides = {
fieldId = "Currency"
value = "CAD"
}
