Dropdown widget not displaying data from properties infotable

Hi all,

I have a dropdown on my Mashup that gets display data from one of my properties which have an infotable as output and Datashape of GenericStringList. It used to work fine but one day it just stops working and I can't figure out why after troubleshooting for half a day. Any help will be greatly appreciated.

Below is the settings for my dropdown widget:
