To anyone having issues with the dlc like cipher legends but has already done other dlcs and gotten the items from them here are some tips:
First copy and place in a backup folder and then delete the extra data folder and start the game most items like the dlc weapons and cipher character will appear as unknown don’t worry .
Second play the dlc that you want to play and finish them make sure you have a save before and after playing it just in case.
Third after completing them copy the backup extra folder to the new one that was created by citra after you deleted the old one and choose the overwrite option.
After this the save file should have all dlc content after and before you deleted the folder enjoy!
