wordpress API bug (pagination bug?)

Hi together,

I think there is a wordpress pagination bug.
I use my wordpress blog to get data via the rest api (https://domain.com/wp-json/wp/v2/posts)

I can get one post by adding this address as request url. But in the app I want to have all posts with pagination. So I used the parameters from wordpress docu and from this site:
https://docs.bravostudio.app/integrations/pagination#wordpress-and-github

Here are my settings:

I've just tested it with the thumb and the post title, see here:

App: "Bravo Sample: Basic app template"

Here are my data binding settings:

**The problem is:
**
I get the 1st post and after that the 10th post from page 1. After that the 1st post from page 2 and the 1st post from page 3.... and so on. But I just get 5 posts at all! If I scroll down the app won't load more posts.

Problem 1: where are the posts between post 1 and 10 per page?
Problem2: where are the rest of the posts after the "5th" post?

Is this a bug?

The response body (wordpress json) looks correct. But the app shows different results.

Thanks a lot :-)
