The 1.81 TB Pool is a HDD that i recently installed ( i need all the Storage) and have not put anything on it yet
No. That's not it.
In 1.81TB storage space pool only 256MB of space is used.
In Disk Management 1863GB (1.81TB) drive used space is 1699GB (not 256MB).
So 2TB HDD is not in the pool.
Other 2TB drive in the system is 980 pro. That's the one in pool.
now was a unallocated space in Disk Management that i formated and initialized and now the NVMe is showing up and working just fine, i have no idea what i did
Either you created a storage space in 1.81TB storage pool
or you deleted 1.81TB storage pool.
Using storage spaces just complicates things. I'm not sure, why you're using storage spaces at all.
