When trying to install kernel headers. it tells me that 5.15.16-1-MANJARO/build exists in filesystem

Hi im trying to install kernel headers with sudo pacman -Syu linux515-headers
and i just get
error: failed to commit transaction (conflicting files) linux515-headers: /usr/lib/modules/5.15.16-1-MANJARO/build exists in filesystem Errors occurred, no packages were upgraded.

Can anyone help me if they could

What is the output of pacman -Qe linux515-headers? Verify if they are already installed.

[aurora@Neptune ~]$ pacman -Qe linux515-headers
error: package 'linux515-headers' was not found
