[HELP]Items disappear (no dupe)

Hello friends, I need your help!
I have a problem with my items.
Any item with count (255) disappears after the exchange.
Example:
I have 150 Rec Runes, I give you 100, the remaining 50 disappear from my inventory when I enter the game again.
But the 100 I gave you does not disappear.
Can anyone help with this error?

Sorry, my Inglish is bad.

You're right.
An admin panel provided here in epvp, was with an action deleting these items.
Thank you very much for your help.
