Reproduction Steps:

0) Use a vanilla bundle with the latest fix pack.
1) Create a structure with file structure.ftl attached
2) Create an empty template associated to the above structure
3) Create a web content with 2 translations (for example EN and IT)
4) Fill all fields in both languages
5) Create least 2 elements for the repeatable item.
6) Save the content as draft.
7) With default language selected (EN): remove one element from the repeatable item
8) Switch to other language (IT): a Javascript error occurs and not all fields switch to the the correct language.

I attached the Javascript error and an xml of the article I used to test the issue.
