Liberty Advanced - Single or dual hinge?

[NWparent]

Just got our daughter a Liberty Advanced catcher's mitt and really wanting to not mess it up by breaking it in incorrectly... is this supposed to be a dual or single hinge mitt? Am I wanting to break it in so the two edges meet (thumb to pinky)? Thank you in advance for any input you have!

It a hybred! LOL. Dual hinge. I will let the experts chime in. My only tip is to go to a batting cage and instead of hitting, have her sit on a bucket and fire those dimple balls at her for a half hour. She will be getting in work and breaking the glove in at the same time.

Dual, IMHO. Photo even shows it as dual (IMHO).
