Steps to reproduce:
- Create a new subwiki
- In step 2 add 2 members in the Members section
- Distribution Wizard will kick in and "XWiki Enterprise - UI - Wiki 5.3" will be recommended
- Click Install and then Continue
You'll get a merge conflict for XWiki.XWikiAllGroup for the 2 members previously added in step 2. The default option is to "Keep the new version of the document" which overwrites your previous added members. You have to select "Keep the current version of the document" in order to keep your members.
