CSS settings are ignored in another plugin

The issue is that I want to create courses and lessons with Bricks and LearnDash, and in general, it works wonderfully. I have created templates and selected the “Post type” under “Template Settings,” choosing “Courses, Lessons…” and so on.

The courses and lessons are displayed, but I have the problem that Bricks-specific CSS styles are removed from LearnDash in the source code. For example, all container settings for Flex, Grid, and so on are simply removed. When I edit the courses and lessons in Gutenberg, the Gutenberg-specific CSS settings remain.

Have I perhaps overlooked something fundamental? Does anyone have an idea?

Thanks in advance
