Soft rejection on elements please help

Recently two of my ppt templates got soft rejected saying to remove any logos which are not social networks such as facebook or twitter… but I went through again and again and removed even whatsapp… by now I have only facebook, twitter and linked in icons included… but it still says to remove the logos… I still can’t find a logo can you please help… any one with the same issue ?

Make sure they’re removed from the mockups as well.

Yes and actually there are no such logos used apart the social media icons
