Keyforms turning yellow, not green

Pupcake

I recently downloaded the free version of Live2d Cubism Editor, and I was watching youtube tutorials to learn how to use it. I was trying to rig a model, and the keyforms, instead of turning green so that I can use them, just turn yellow. This is not the first time I was using keyforms, and it worked well before. I'm not sure how to fix this. I am on a Macbook from 2014, so my laptop is pretty old and could be the issue, but it was working before.

Hello, @Pupcake
Thank you for your contact.
This is Live2D Support.

The yellow keyform indicates that multiple objects are being selected and not all keyforms are matched.

Please take a look here.

The yellow key forms are not necessarily an error indication.

However, if you are experiencing what you believe to be faulty behavior, please provide details of when the yellow keyform occurred.
