As usual, Spanish data on Espacenet is quite patchy. Experience has taught us that the priority date purported in the inventor's results column is more than likely the filing date, of the patent in Spain. This is fairly peculiar to Spanish data. The purported publication date is likely the date granted. This is less peculiar. British, data, on Espacenet, follows this same pattern, while the publication date on French patent results, is usually the actual publication date shown on the original, as differentiated from the date of acceptance or granting.
