As you can see I am trying to insert the Lightbox display positioned as above. But in the browser they are stacked up on one point. Someone expierenced this issue too? It's just the x-axis. Using Muse 2015.2. It's the standard widget.
Just to be sure, are you on 2015.2 or 2015.2.1? We have seen a few issues with widgets in 2015.2.
To confirm, select Help > About in Adobe Muse.
I am on 2015.2.0.877
It was a known bug. You need to upgrade your Muse.
