citation style change problem

I have been using Endnote the last months. My chosen citation style was Bluebook. Now I want to switch to OSCALA. I have downloaded it already. Even though it appears as the selected output style in Endnote when I insert the citation to Word it is formed according to Bluebook and not OSCALA. One by one I need to change all the citations and turn then into the OSCALA format. IS there a way to change all the citations at once? And why is the citation inserted into Word in the Bluebook format even though I have selected OSCALA? How can I solve this problem?
