Synchronization error

My desktop has the synchronization set, but some error in the system deleted all the demo scripts that come with Ctrader and my scripts as well.

My questions are:
1 - Why does one script have a cloud marked in red and others not, even though they are all empty?
2 - How do I recover the deleted scripts?
3 - I can't open these scripts to rewrite them.
4 - In the second print I can't see the option to change the script name anymore.
Please send me the solutions about these problems.
Thank you
