skill restriction [Wedding]

[Tio Akima 74]

Guys
I'm trying to use the skills without restriction
WE_FEMALE
WE_MALE

I removed the marriage restrictions
And I changed the skill to use with friends.

I edited on skill_db

I removed

SkillInfo: {
Wedding: true
}

and changed to:

SkillType: {
Friend: true
}

but it still does not work
Are there any other restrictions?
