ammunition item not working for reloadammo mechanic after logout

if I use /mm item get dispenserammo, reload mechanic works correctly, but if I have items in inventory OR in a container and logout of server/log back in, I get the onfail response from the skill with that item in inventory. if I then use /mm item get dispenserammo again, I will get new ammo that doesn't stack with the previous; and does work until logout/login again. believe it's just me when I had the item, i'm opped and others are not. i can try to test this with other op users on server if needed. are there any perms that can affect this?
