Oh, the prophecies attributed to Our Lady of Good Success are extremely questionable. There is no proof those prophecies existed before their fulfillment.
Yeti, you may be interested in Father Purdy's series of talks on Our Lady of the Good Success of the Purification. He traveled throughout Ecuador to translate the 5 existing hand-written copies of the 400-year-old docuмent. The original was lost but he was able to compare the 5 exisiting copies which are also 400 years old. He knows Spanish, which is why he was able to translate the correct name of Our Lady in this apparition.
Another translation was done, but it is unreliable. It was done by Marian Hovart who translated it from a copy of a copy that was in Portuguese. Her sloppy translation of a copy of a copy mistranslated Our Lady's name as Our Lady of Good Success, which has turned into a kind of good-luck name for people who want "success" in their businesses or gambling.
