Removing palm trees from Magnolia Promenade

Hello! I am quite new to Sims 4 Studio, and I wanted to remove the palm trees from Magnolia Promenade. I was able to do that, I replaced the trees with another kind of trees, but I can't get rid of the lights/ornaments/whatever they are that were on the palm trees, because I can't find them anywhere! A picture of the problem:




I was sooo proud of myself for actually managing to replace the palm trees, but those lights are really bugging me! I would truly appreciate if anyone could help me out.
