Extract moving lights and null from C4d to AE

hello eveyone,

I have a project with an animated character.

my character is moving from on point to another and i want to track an object on the character.

I created a light and parented it to my desired object. in c4d the light follows the boject perfectly but when i go to AE and extract the 3d datas the light comes up with only a few keyframes which is not the lenght of my composition. anyone knows how to solve this?

Additional infos: i am on c4d R25 and AE 2021

Animated the character using mixamo

Character as multiple mixamo animation combined (add motion clip + pivot)
