Store launches and links to Dolby Atmos app when I change Spatial sound to Dolby Atmos

I just received Creators Update, and I installed Dolby Atmos for the demo, everytime I change the spatial sound to Dolby Atmos, it launches store and links to the Dolby App. But I already installed the app, and I have confirmed the demo, still 24 days remaining. I reset the app once, I could only use Dolby once. After a restart, the same problem came back. I Googled but no discussion with same case like me.
