Messy Custom Samples Widgets in Experience Builder 11.1

[DeanMoiler]

Hi Everyone,

We've been looking into developing some custom widgets in ExB and have noticed that there already appear to be a lot of them available that we didn't create:

I can see these custom widgets in 11.1 on a couple of different portals, but not on a few 11.2 portals. 

They appear to be available in the "samples" folder within the deployed version of ExB at this version:

Ideally we'd not want these widgets to be shown in the builder, only the custom widgets we develop.

Does anyone know what these widgets are? Is there a "developer" option I've switched on by mistake somewhere perhaps?

Thanks,

Dean
