Scorm 1.2 api does not initialize correctly when the first sco to launch is in the third level of the scorm toc

I have a scorm with 3 levels in the toc. My first sco to launch is inside the third level.

When you launch the scorm the sco display without showing any issue but the debug tool shows that it is not well initialized :

Afterwards when I select another item of the toc I get a LMSInitialized 101 error code.
