Try requesting it back via the API, I expect it will look correct. This might be an issue with the display, which metafield editor app is this?

I think this article describes the issue and a possible fix: https://www.agwa.name/blog/post/fixing_the_addtrust_root_expiration   We will also look into being able to accept this cert chain from all systems.

Can you provide more detail? What happens when you use the REST API? Support and other forum users will need that to help you.
