You have been misled and deceived by the false teachers. The date 537 BCE is is the accepted date for the Return 0f the Jews to Judah thus officially ending the 70 years.Jer. 25:12 only comes into effect after the 70 years had ended in 537 BCE and not 539 BCE at the Fall of Babylon for it begins as a qualifier "But when 70 years have been fulfilled" and Dan 9:1-2 refers to the ending of the 70 years after Babylon fell for Daniel observed the matter in 'the first year of Darius'.
