Remove encryption setup on a lvm/luks partition

On my linux machine, I have setup disk encryption using lvm/luks. However later I delete one of the partition and format it to NTFS in order to use it on Windows (as I have dual boot linux/win10).

There is no problem so far except that I have repeated errors during boot which says

"systemd-cryptsetup[1458]: crypt_load() failed on device /dev/disk/by-id/ata-ST1000NM124-1EJ264_W722DT5A-part9.
systemd-cryptsetup[1458]: Failed to activate: Invalid argument"

How can I stop the system from trying to find the partition I have already reformatted so to get rid of this error?

The error doesn't prevent my system from booting at the moment though.
