Pre Condition

1. There is a Web Content created based on a migrated structure which contains nested field with 1 level
2. There is another Web Content created based on a migrated structure which contains nested field with more than 1 level

Steps to reproduce

Please, watch the video to reproduce the steps: WC-Missing-Nested-Fields.mp4

Expected result

The Web Content based on that migrated structure must display the fields that were added as nested in the structures

Actual result

Notice that the Web Content created based on migrated structures created with 1 level are not rendering correctly. They don't show the fields which were added as nested. This is happening with structures with levels of nested more complexity (we've tested with 2, 3 and 4 levels)
