Studio deployment from Admin Center express a bad warning

• I download a cap offline distribution 5.5.
• I select nuxeo DM module during the installation
• I register my instance and link to my studio project toto
• I configure toto as target platform Nuxeo DM 5.5
• I release my project
• I connect to my instance with the Administrator account
• I go to the Nuxeo Studio tab into Admin Center > Update Center
• I click on the download from the production mode
