change the css in the theme doesn't work

I am using angular 7 version based ngx-admin. I need to change the ul 's padding-left from 1.25rem to 0rem.

I put the css inside the pages.components.scss as below
```
/deep/ .nb-theme-default ol, .nb-theme-default ul {
padding-left: 0rem;
}
```

The new css has shown to be active when refreshing the browser, but the css still show the effects as before.

How could I solve this little problem
