Field not translating correctly into new layout
Description of the issue
We created a new layout that incorporated some core fields defined for the initial layout. Three out of four fields translated the data correctly, but the last one (called "Themes") did not as in certain cases; some piece of data was missing, or it was mixed up with a different field (which was not listed within the new layout), or it added irrelevant info e.g. X. The layout we are using is the List Layout.
Steps to reproduce the problem
We tried to duplicate the initial layout and subsequently delete the field we did not need, and yet again the translation of the "Themes" field was not correct.
The initial layout presents the "Themes" field into a checkbox set, and what we'd expect to see is this field as in a list for the second layout. Furthermore, this second layout should show only the checked themes in the initial layout.
Some fields within the second layout are correct, some others (most of them) are not because the data is wrongly translated.
Exact text of any error message(s) that appear
No error messages appear.
If we keep the checkbox list within the second layout, "Themes" translate correctly. As soon as we use the list, data gets mixed up.
Truly need serious help!
