Certain Rigs not animating upon Sequencer Render

I’m doing a scene for a short film. When I render out the sequence, only some of the rigs are moving in the scene, while others do not. When I play the regular level editor viewport, all of the animations play just fine. Any fixes or things that might be causing this?

if the objects are playing back blueprint animations, they may not play for various reasons
if they’re added as tracks to the sequencer, they should play
