Background:
We have a sitecore 6 installation with a bit of custom code to detect devices (and origins), and switch to a different (custom) device definition in sitecore. This has the effect of changing templates, and controls where appropriate.
This all works fine.
However.
When we select a node in the content tree, go to the Presentation Tab, click Details to get the Layout Details windows, then edit a device item to add controls we see that duplicates are being added to the devices – not just the one we are editing either. It seems to “double up” what is there – but it never changes the “Default” layout.
I have checked the usual suspects (i.e. all connection strings are correct, pointing to the right databases) but I still get duplicates on saving. The duplicate does not appear on edit – but save – it seems.
Any suggestions on how to track this down, as its causing a nightmare for us.
Sitecore Version : 6.4.1 (rev:110324)

This is a known issue that can be solved by specifying a layout (Mobile Layout and Main Layout, in your case) on the standard values of your template.
