I am noob

1. I've included my Fibaro Relay Switch 2x1.5kW FGS221 2.1 - 2.3 and it is but only 20 seconds.
When I will turn on one or both switches stay turned on only for 20 sec and than getting off ??
where is the problem?
Where can i disable that auto thing ?
2. this problem was as well in 1.3.1 and 1.4 when I try to rename my device it is renamed but only for the "session" , when I'll reload page it is again for example "Device4". I did "apply changes for this device"...
3.When i try to use button "switch all on/off" a get error message like this http://locosp.dyndns.org/blog-grafika/r ... /error.png
4. Maybe I don't know much about it bu I think here http://locosp.dyndns.org/blog-grafika/r ... razpis.png should be only one position, or no ?
5. Is it normal that "change device type" do nothing ? http://locosp.dyndns.org/blog-grafika/r ... getype.png ?
6. I think last

Sorry for my English ...
Thank You in advance
