Problem with iShow u audio capture

Hey

I have a problem with Show u audio capture, it causes problems such as: not being able to control volume and especially when listening with bluetooth headphones (beats powerbeats pro), alert/sound effect volume is different from general output volume. When connecting with bluetooth headphones, sometimes the output is still in mac speakers, but input is in headphones' mic so I have to change it manually through the preferences which I don't think is normal, because it wasn't like this before. And several other audio related problems that happen not so rarely too.

I followed all the instructions properly from the official site on how to uninstall the software, and I did everything successfully. But I still seem to have the software inside my mac:

Any help would be appreciated.
