the Server marge on SA is Complete but my 6 extra slots tha i get on ark store is gone how can i get them back?
After moving 6 characters out of the Universal Storage, you should have the option to start using the tickets you purchased for any other characters. Essentially, everything was reset in terms of slots unlocked but all the tickets were refunded back to the account.
Hey there @black.frolzen, Welcome back to the forums!
As @Masn mentioned (hi, again, and thanks again 
), Character slots will reset to the default 6. Additional character slots that have been purchased will be returned to the player as Character Slot Extension Tickets.
More details about the merges can be found here: Server Merge Details - News | Lost Ark - Free to Play MMO Action RPG.
I hope this helps, and let us know if you get your Char slot extension tickets back.
