Publishing a language to an existing space replaces Confluence page titles with translated titles

Steps to reproduce:

1. Create a space with 1 version and 2 languages: English (default), German

2. Translate a page in the space to all languages

3. Publish English version 1.0 to a new space

4. In this «new» space add German language

5. From the «old» space publish German language to the existing «new space»

6. Opent the «new» space

7. Open View in hierarchy

Expected result:
Confluence page titles stays as English

Actual result:
Confluence pages titles are replaced with titles from the last published language

Workaround:

• Publish all languages instead

• Republish English (this would replace the new content with the content from the «old» space!)
