My son graduated last year and did not send any of his dual enrollment college transcripts to colleges. They just used the high school one.
Once he matriculated he sent in his AP scores and DE classes to see what college requirements they would cover. For one DE class, the college asked to see the class syllabus before rendering a decision. Our high school provided it. On that one, they did not give him credit for a particular college class, but just awarded him general elective credits. Two fewer classes he needs to take to graduate.
