Why am I getting different outputs when using CUSIP vs RIC?

In the code below, the volume data which we get is different, when I use the CUSIP vs when I use the ticker. Can you help me in getting the correct information? I want to use CUSIP, but want to get the information which is returned when I use the Ticker as the universe.

import refinitiv.data as rd

rd.open_session()

df = rd.get_data(# universe = ['00032Q104'],universe = ['AADI.O'],fields = ['TR.TickerSymbol','TR.Volume', 'TR.Volume.date'] ,)

display(df)  

Thanks so much for any help that can be provided.
