Custom Character (adjustment points Issue)

I have created custom character which is rigged and caged , but i have problem with adjustment points

I placed them properly in blender image hosted at ImgBB — ImgBB But when i export it and import it in studio all the adjustment points are not in proper position image hosted at ImgBB — ImgBB

I have parented adjustment points with bones ex: hat_Att parented to Head bone …etc and applied transformations and centered pivot

everything works in avatar setup preview except accessories because of adjustment points are not in positions …

??? I can’t upload images
