[Solved] Unsubscribe All Users from Specific Threads

[Stratis]

I have an issue, when I want to delete subscribes from users it says "No Threads Matched Your Query" This is wrong, because I see that member is subscribed to that thread.
I thing that i cannot delete subscribes that they have the option "Notification none" I don't know how this option is there for users. That's what I see to mine two other user I have.
If option is something else except Through my control panel only, no problem.

Any help why this is happening, Thanks
