Why would my export button disappear?

Hi everyone,

I have a problem with the export of table data in one of my builds.
Previously the “Export” button was working fine and then just a couple of days ago it has vanished.

I investigated on the back end and retraced the set up of the “Export” button (As per the instructions found here… http://help.skuid.com/m/components/l/102563-export-data-from-a-table ).

I have been working with my manager on this and still no success in fixing the issue. 

Is this a known problem that has occurred to anyone else? If so can anyone give me some advice on how to mitigate this? 

Many thanks, 

Matt
