convert-reg and convert1reg not working

[phate89]

Hello, I started using kitty a year ago in portable mode and it works well.. Lately I started using winscp and I discovered that with registry mode i can use kitty instead of putty for terminal sessions straight from winscp. The problem is converting to registry mode since I have a lot of stuff. So I discovered "-convert-reg" command that should move everything from files and folders to registry. I tried and at first it seemed it worked well, I found all my sites. The problem is that when I load them there's nothing. So I looked in the registry and it seems at least all "Hostname" keys are empty so something went wrong with the import.

I know it's not officially supported. I then tried convert it failing. Is there a way to import files without manually adding the info? Thanks
