Set CPT to show the e-learning as validated on the LMS

I created a E-Learning with questions on CPT and posted in on my LMS (Talentsoft).
The E-Learning is working and i have set the Exit Button via Java Script with the code SCORM_CallLMSFinish();

When i click on the button the e-learning is closing but it stills appears as ongoing and not as finished on the LMS, even if all questions have been answerd correctly. And when I try to redo it, when I am on the last slide, the e-learning shuts down automatically without any clicking.

Can you please tell me what I have done wrong?
