Abbreviations and full names mixed in bibliography

I am writing in Microsoft Word using APA style, which requires the journals to be displayed in full names in the bibliography. However, the automatically generated bibliography abbreviates some journal names while keeping others in their full name. It is really confusing.

@Nashi_Shuai, have you checked if the full journal name is present in the affected references’ metadata? You can do so directly with the Word plugin or from your library by selecting and hitting shift-e. Let me know.
