[Vuejs]-Prerender-spa-plugin shows 2 pages on one route, instead of only one, in quasar framework, vue 1.x

Okay, the problem appeared to be in the vue-helmet plugin. I’m not sure why, but before I installed prerender in was working all good (vue-helment is used to manage metadata on separate pages). But when used together – they are making conflicts.
So, I had just find another solution for managing metadata, which also works with pre rendering.
Now, everything is fine
