CCC Moving to a new SSD

I've done it in the past successfully. It's not working with this new SSD:

Moving from a:
Samsung SSD 256 850 Pro

to a:
Samsung SSD 512 860 Pro

When I try to set it as the boot device on my Bios it shows up like this:

It doesn't show the UEFI OS part of the original SSD

These are the properties from both (Sierra is the old one):

Any idea why this is not working? Both drives are formatted as APFS.

You sir are correct. I don't remember doing that before, but I guess it my fault. Thank you, and sorry if this was too obvious.
