please help: Garmin Connect - Device "Activities" Displayed

Hello All,  I have searched and used trial and error but can't find a fix for this:

I have a Garmin Connect 35 device.  I thought added my activities to the device to be displayed so I can manually start tracking an activity.  However, it has "running indoors" and few other activities I do not do, but does not display, nor will it automatically identify and track, activities I engage in such as interval training and lap swimming.  

I so much appreciate any and all help you can provide.  

Thank you.

Yours in good health and wellness,
