From the pic it looks like your Phantom power (+48V) is on - which it doesn’t need to be. It also looks like you’re clipping - perhaps the gain is indeed too high. Of course this could just be deceiving due to the lighting.
Perhaps you’re running the MP3 track too hot and need to turn this down. Mixing isn’t just simply turning everything up.
I understand you’re using a template - try to follow the signal chain of the Bass channel in question including all plugins used in the template.
