We will be happy to assist, however we need a sample project with your exact setup and a couple of pdf files for the template of the rotator. Embedding pdf on a page makes the pdf files heavy weight objects and it is the probably reason for all files being on the page, i.e. bleeding-through. If this is the case, I am afraid that we will not be able to help at all. However, we'd like to look at your project.
