Two Paragraphs fields in Mercury Editor cannot be edited

Problem/Motivation

Description:
I have a content type with two Paragraphs fields:
• field_content (Paragraphs) (img 1 - )
• field_hero (Paragraphs) (img 2 - ) -> cant open

Expected behaviour:
When I add a paragraph to field_content, I can see and use options such as column layout, edit, clone, etc. on the right-hand side of the Mercury Editor.

Actual behaviour:
When I add a paragraph to field_hero, these editing options do not appear. The field is therefore not editable like field_content.

Steps to reproduce:
1. Create a new content type.
2. Add two paragraph fields: field_content and field_hero.
3. Create a node with this content type.
4. Edit with Mercury Editor.
5. Add a paragraph to field_content → right-hand column with editing options is available.
6. Add paragraph to field_hero → right column is missing, editing not possible.

System information:
• Drupal version: Drupal 10 (latest version)
• Mercury Editor: 2.2.4
• Paragraphs: latest version

Question:
Why does field_hero in Mercury Editor not offer the same editing options as field_content?

Does anyone have any ideas?
