The testing environment has the following Drupal version and modules installed.

• Drupal 7.52
• Entity Translation - 7.x-1.x-dev
• File Entity - 7.x-2.x-dev

Steps to replicate:

• Add some Languages to the website.
• Add an unlimited File field to the Article Content type.
• Add an unlimited Image field to the Article Content type.
• Create a new Article and add multiple files and images.
