Help with rejected presentation template

My first upload (PowerPoint template) got (soft) rejected due to “Your submission contains apparently trademarked names or assets (logos, etc) not adhering to our content policy.”

I have checked my deck multiple times; there are no images, logos or anything that is trademarked in it. The only images used is (1) mockups of iphone and macbook that are free for commercial use AND does not include the apple logo in neither one of them (2) a graphic image that I have produced myself. Can it be any of these?

Let me know what you need to help me out.
