Need help! Envato Elements Premiere Tranisition not working

Hi there - I’m struggling to get the Dope transition to work properly, and wondered if anyone can help - I’m sure there is a really simple answer, but just not working at the moment. I bring in the transition sequence I want, but it has as default the Envato .gif image (the elephant one), which naturally I do not want. However, if I delete this, there is no transition applied to my clips underneath. Their video guide did not help, and was technically incorrect.

Any help hugely appreciated!
