Skyrim GUI versions erasing additionalConfigFile= parameter

[Techuser]

Seems to be a bug that somehow only happens to me. I guess the gui works by creating a temporary userconfig.ini while you edit it? Well I found that if I leave AdditionalConfigFile=userconfig.ini blank, it will ignore my enbseries.ini settings and always start with some default parameters when I check the gui (so it must be giving priority to a userconfig.ini that doesn't exists anymore instead of my enbseries.ini?). The problem is that after I tweak through the gui and save it, it stores the new parameters on the enbseries.ini BUT erases AdditionalConfigFile=userconfig.ini from it, and to read my tweaks again I always have to manually add that line in enbseries.ini everytime I save the gui and leave the game.

Any ideas?
Already checked for other enbseries.ini in my HD, it's not read-only, and it's not installed on program files. Already tried wrapper and injector versions and got the same thing, they always come with AdditionalConfigFile=userconfig.ini by default but this parameter gets blank after I save in the gui.

Thanks for report.
