filter by category in latest articles are not taking into account the app.config

[i-salameh95]

Description

using latest-post plugin with app.config and category specified, when click on category it redirect me to page saying that no posts is found, the website uses 2 app config, one for news and one for another blog. each of those config have it's own categories.

Steps to reproduce

1. create 2 app config with categories in them
2. in another page insert latest posts from config1 with category ( from config1)... also another bug here: filter by category contain all cateories by config 1 and config2.
3. click on results meta category, it will direct you to config2 page saying no posts found.

Versions

django cms : 3.11
django version: 3.2

Expected behaviour

the category should direct to website/news-and-activites/category/news/

Actual behaviour

the category direct to website/health-blog/category/news/
so it direct to category slug inside another config.
