i don't quite get how that works. i put both my mom's and her dad's dna on here but yet it says confirmation of how they are related is still needed. my grandpa shows up on the top my mom's dna match, and ancestry predicted them to have a parent/child relationship which pretty much confirms that my grandpa is her bio-dad, but yet the page for my mom acts like i never linked my grandpa's dna test t the tree, and says he still needs dna confirmation.
what's up with that and how to fix it?
