Help with Appending rigs for GFX

Hi there developers! I was facing a issue with appending a rig into another rig file for a GFX, while i imported the new rig a whole bunch of shapes connected for the rig showed up.

I’m not sure how to get rid of it and what is for, Please consider taking a few minutes to let me know what it is that im doing wrong if you do know.

All I did was append the rig, while appending it go to object form the files of the rig, select all and then press append.

(using SoftGB’s rigs)

Appending method

Thanks in advance!

I just select all the unnecessary objects, move them to its own collection, and hide them. The reason you cant delete them is because they are the custom shapes of the bones

Alright, so now what should i do?
