xCode 9.3 Importing XLIFF file into a project with multiple targets is not adding all strings

I have a project that have two different targets: target-A and target-B


When I export XLIFF file for translation all the strings are included whether they are defined in target-A or target-B.


However, after the translators export the translation file and I import it, the "localizable.strings" file only contain strings which are defined in target-A, so every localizable string that is defined in target-B and not in target-A is not imported.


We have never had this issue before xCode 9.3, we used to import and export successfully,


What could be the issue, is this a bug in the new xCode or there is some kind of a trick that I should do?


Thanks in advance
