Common App problem! (recommenders)

So at the beginning of application season, I was pretty confident as to which colleges I would be applying to. In the common app, I invited an “other” recommender (a college professor from an internship) to all of these colleges that I could. The professor quickly submitted his recommendation and that was that. BUT, recently I decided to apply to another couple of schools and I added to my common app account with a big problem. When I went to the “other” recommender section of these applications, I was not able to assign the same professor, who had already submitted letters to my other colleges. Common app said that there was already a recommender with this info and email that had submitted earlier. How can I get this same letter to go to these colleges if it won’t let me assign the recommender again?
