Advanced layout builder bahavior issues in LearnDash content editing

Hi there,
I’m currently editing material within a LearnDash course within the Enfold theme environment using Avia Layout Builder.

Most things work fine so far. However, introducing Text Blocks results in the Text Block editor lightbox to be too wide and thus partly covered by the admin menu on the left. This behavor makes introducing text blocks quite awkward. The same happens if one expands the Avia Layout builder to full screen. in that case the layout area is partly covered on the left side by the admin menu.
I’m not sure if other Avia elements are behaving also that way. However, all other elements I have used so far within LearnDash lessons behave like they should (under non-expanded Avia).
Is there any way of fixing the Text Block editor lightbox and the fullscreen bahaviour?

A secondary issue is that within LearnDash Content editing the editor toolbar (classic editor) is not sticky when scrolling within the editor. I assume this is a result due to the fact that Learndas content editing includes a unique header element where the title is set which also includes to switch between two tabs “editing content” and “settings for the content”. I assume, this is designed for Blocks editor. Nevertheless the question if there is a solution to fix that.

Thank you and Best
Michael
