Import settings in WebUI has no effect

Hi,
Yesterday I've switched to Hyperion.ng (really nice improvment over Hypercon) and set up everything I needed.
But because of to much fiddling, Hyperion has crashed and didn't want to start anymore (every time it froze on the rainbow swirl effect).
Not a big deal since I had made a backup of my config with the export button in the WebInterface.
So I've reinstalled everything from scratch, and imported my config backup in the WebInterface.
-> I've seen the message telling that everuthing will be overwritten, but in fact, nothing happend, settings stayed the same as the default ones, I had to do everything again manually...
(I've checked the JSON file with Notepad++ and I can clearly see my modifications).

Second problem I have : everytime I go back to the webinterface, in the LED hardware tab, all values regarding my number of leds is reset.
On the right, total number of led and placement of index0 is correct, but for the top/bottom/left/right settings, they are back to default...
That would be really great if theses settings could be filled with the numbers defined previously.

Thanks.

Up...
Still no clue why it doesn't work ?

Thanks, that's exactly what I was waiting for, a simple answer instead of nothing at all.
And no I did not expect you to solve the problem immediatly.
Have a nice day btw.
