When you try to add a collection block to your landing page, there's no way to choose the content(s) you want to put in that collection.
You can select content, but the "Choose this content" button in the right part remains disabled.

This is affecting to ezstudio 1.13.2 and also 2.1.0. See pic

Steps to reproduce

• Install ez enterprise with studio-clean either for 1.13.2 o 2.1.0.
• Edit the home page and add a collection block.
• Try to add contents in that block
