We identified the problem with scenes not being shown. It was a bug in the data migration from the old to the new format. I put a new firmware, 371, that fixes this. If you upgrade from 320 -> 371, it won't happen. If you already upgraded to 370, then you need to upgrade to 371. Then edit some thing (like say, change a room name) and click 'Save', and as part of the save it will detect the malformed data and correct it, so you can reload the page and the scenes should be there. Also, the issue with the location should be fixed as well.
Regarding dashboard not matching, I'll look into this.
As far as the square icons... The icons are only temporary until we get good ones in the new UI. Each square indicates a 'job' (ie some activity or command for the z-wave device). The 'C' icon is for the configure job, the 'P' icon is for the poll job, and there are also icons which appear next to the node when the device is sent commands: 'ON', 'OFF', 'L' (for level like dim level or temp level), and 'MISC' (for other jobs). The C job is always shown so you know if the device was configured. The 'P' and other command icons appear only if you check the boxes under Advanced, Logs.
The color indicates the state of the job. Gray is 'queued, waiting to run', Blue is 'running', Green is 'finished successfully', Red is 'failed'. You can hover your mouse pointer over the icons to see a human readable description of the state and the error message if the icon is red.
This is part of the new back-end for the new UI. The goal is to provide feedback so you always know if the command gets through or not. If a node is flaky, for example, you'll see that sometimes your command/job icon turns 'red' if, after 5 attempts, Vera still can't get an acknowledgment from the node that it executed the command.
