Efi partition issue

Trying to instal Manjaro, dual booted with Windows.

Windows is already installed but Manjaro is still asking me to make an EFI partition, I think it has something to do with /dev/sda2's type coming up as "?" on the Manjaro installer:

What should I do, and what am I doing wrong?

Thanks!
