Help - Sword Trails wont load in game

Hello all, I am looking for help with getting a sword trail to load into my anim notify on a montage.

I have tried multiple methods of doing this however I cannot seem to get it to work in game. I think it may have something to do with the montages are bring run through a actor component called BPC_Attack System based on the Gorka Tutorials.

I can get cascade versions of the trail to load in the montage editor/viewer however these do not appear in game.

Below I have attack my blueprints to try and get the trail to work off of niagra and custom notify states. I have also attacked a screenshot of my BPC Attack System and BP Third Person for reference.

Any assistance or ideas to get this to work would be massively appreciated!
