I've recently upgraded my angular project from 5 to 8. My project was also having a dependency on bootstrap v4 (Since I've used ngx-bootstrap). I had to upgrade the primeNg from 5.x.x to v9.2Lts.
Now that the primeNg has changed it's flex grid implementation from ui-g to p-g, similarly the responsive usage of u- to p- . this p- class is common in both the frameworks ... which is conflicting the UI.
