"Update Features" removes all my Features?

I still have the issue that it removes all features when use the bottom “update features” button. But a temporary workaround is to use the features panel. But then it automatically generates this code:

languagesystem dflt dflt;
languagesystem dflt MAH;


script dflt;
language MAH;
lookup locl_dflt_0 {
sub commaaccentcomb by commaaccentcomb.loclMAH;
} locl_dflt_0;

All the functions has some sort of error. I’ve tried to uncheck “Generate features automatically” and then remove them, but it still displays errors.

What to do?
