Dragon Soul bug ? or game?

[WhoIsNice 9]

Good evening, I ask help to a problem that does not even know where did I go wrong
but it is the following,
I do not know where I changed and what, since I have only been tinkering in quest's but from 1 day or 2, that when I invoke an item that does not exist, the chat does not appear to indicate that it does not exist and when I try to create a stone dragon soul, he invokes well but when I try to evolve, the stone appear in my inventory

Sometime when i try to invoke a dragon soul item ( ex : 164400 ) if i invoke with +1 or +6 wtc ( 164410/60 ) the item appears in my inventory and with 200 stacks

 

Some thing's in sysser : UseItemEx: Item type NONE RSl

                                     this: #154460 RSl wearflag: 1801675124 cell: 36

Soo, i'm asking for help who can understand this error...

 

Thank you for the help and kind regards
