Hi Juan,
Please check if Spanish is added to your Datawarehouse settings in System Options. If it was not added, add it, and run DWH job until completion.
Normally this should be enough to solve your issue. Please note though that adding too many languages can result in performance hit on Load DWH job, so add only the languages that are really needed.
Please let me know how it goes.
Kind Regards
