so after i made maybee's model in paint 3d i saved it using the default save function

however it appears that i wasn't supposed to be doing that as now maybee has been saved as one singular object, meaning that whenever i click on a certain part to move or edit it, i end up clicking on his entire body, making it impossible to animate him by moving any of his individual limbs. opening him in blender, he's completely fine, it's just paint 3d that thinks he's one singular object for some reason. when i try to use the ungroup button it doesn't work, it's just greyed out permanently for him. i've tried resetting paint 3d yet the issue still persists.

if there is any thing you can do to help my Boy.. ..... it would be dearly appreciated

here is the link to the model if you want to Fiddle around with it
