apparel & accessories additional data for google listing

Hello,
i am tring to use your awesome new google listing&ands plugin(thank you for that, and we need more native plugins like this).
I need to add age group, color, gender, size to fix the Google listing issues. But, Do I need to add it one by one for each variation? I added the values to the categories, but it doesn’t seem to have fixed the issue.
What should I do to fix the issues?
