After flashing phone, "My Shortcut" button does not work
 

I just finished flashing and unbranding my SE K790a with no difficulties. After starting up my phone again I noticed one thing that wasn't quite right.
The "My Shortcut" button doesn't open My Shortcuts anymore, it opens up an internet browser.
I'm not sure what could've caused this. Can someone help me out? I'll upload a video demonstrating what I mean.
