Lost of information when importing Construction Library from IDF to OpenStudio

edit

Dear All,

I used Window 7.7 to model different types of glazing. I imported them in E+, creating an updated idf file (9.3.0 and 9.2.0). Finally, I tried to import the construction set to OS.

My problem: I lost many constructions! My IGUs are not in the library, even if I can find the single glass panes I used. Could you explain me what happens?

(OS 2.9.1, idf file : 9.3 and I tried 9.2)

In advance, thank you very much!
