Echomap 75sv uhd with gt8hw-if ducer auto select ducer showing dual beam

[ride.race.live]

So i got my echomap 75sv set up for ice  with a gt8hw-if  ducer  and while setting it up i saw the unit selected dual beam tranducer.   (Unit auto detects transducer)   when i go to manually select the ducer there is an option for gt8hw   however i know  theres 2 options for gt8hw...   you have the IF  which is for ice fishing  then you have the IH   which is the in hull ducer.

So which setting is correct?
The unit on auto select  selecting dual beam   or should i manually select gt8hw  even though it doesnt specificy if its for the IF OR IH.
Thanks!!

update: I ended up contacting garmin and they told me to manually go select the GT8HW transducer
