I try to create a parent item for my pdf file. But when i click on the "Journal" or other modules and try to type in some information, it goes wrong and always skip to the "Abstract" module. And the "Extra" module displays "abstractTranslation" automatically everytime i click on other modules except "Abstract" module. It seems that i can only type the information in "Abstract" module. It makes me crazy. How can i deal with it?
