Why did my prototype triggers change from "Tap" to "Keys & Gamepad" ?

I put together a prototype and did everything consistently. But when I shared the XD link or previewed my prototype the links weren't working on a few of my elements and I couldn't figure out why because I could clearly see the link. Finally I figured out that a bunch fo them had changed to "Keys & Gamepad" as the trigger instead of "Tap."

Did I do this accidentally via a shortcut....? I use things like "V" to get the select tool and "T" to get the text tool. How did this happen? Or is it a bug? 

FIRST TIME FILE WAS OPEN:

[Text + Icon]  --- was broken... figured out trigger had changed to "Keys & Gamepad"

[Text + Icon] -- trigger was correctly applied as "Tap"

[Text + Icon] -- trigger was correctly applied as "Tap"

[Text + Icon] -- trigger was correctly applied as "Tap"

[Text + Icon] -- trigger was correctly applied as "Tap"

AFTER I QUIT AND REOPENED: 

[Text + Icon]  --- was broken... figured out trigger had changed to "Keys & Gamepad"

[Text + Icon]--- was broken... figured out trigger had changed to "Keys & Gamepad"

[Text + Icon] -- trigger was correctly applied as "Tap"

[Text + Icon] -- trigger was correctly applied as "Tap"

[Text + Icon] -- trigger was correctly applied as "Tap"
