Creating Custom Activity can't set icon and type

Dear all, 

I'm trying to create a new activity following those steps 

https://www8.garmin.com/manuals/webhelp/fenix5/EN-US/GUID-7B574BD8-05BB-410D-9A2A-7646D0B037B6.html

But, i'm not able to do the step 3, i can't set the activity Type, when I sync, activity comes to Garmin Connect with 'others'.  Yes, i can change it on the web, or in app after activity, but, i want to set a Activity Type as default for this new Activity.

Also, i want to set an Icon but i'm not able to do this. 

Any help on this?

Many thanks! 

Regards,
