Audio droping from my AI footsteps when I use attenuation

In my project, I have an AI that roams and chases the player. I added footsteps to the AI but I don’t want to hear them everywhere so I added attenuation to the meta sound that plays the footsteps. I am using the AnimNofity blueprint to play a single step every time the AI takes a step. This works wonderfully for about 1 minute then the audio cuts out of the falloff distance and the sound can only be heard in the inner radius. Has anyone else come across this issue? (Also I did the same steps in a new project and it works fine)
