Share misreporting freespace

HI Everyone.
How are you?

I have in issue where i have a 10TB share for backups.
Its 3 drives configured as 1, raid 0

So what happened is the drives got full to teh point where no more data would copy to it.
I cleared some space, 50% actually but the share from my PC still reports its full and wont copy large backups to it…
But on the dashboard of the Rockstor you can quite clearly see it not full.

Any suggestions please?
I included a picture for clarity.

Thanks so much
