Relations are not displayed on Summary tab since entities are available

Relations are not displayed on Summary tab anymore when the semantic entities and smart search packages are installed on the same instance. This occurs on the intranet. Here is how I reproduced it locally:

1. Installed Smart Search + reboot
=> OK
2. Installed Hot fix + reboot
=> OK
3. Installed Categorization package + reboot
=> OK
4. Installed Semantic entities package + reboot
=> KO
5. Uninstalled Smart search + reboot
=> OK
