The saved point in my course doesn´t work

I have a course that has 3 sections and 1 main slide, every time you complete a section you return to the main slide and then unlock a new topic. It works great, but when you get to the end of the third section and accidentally log out of the course, it returns you to the last question in section two. The problem is that there is no explanation for that error. The properties of each slide state that you return to the saved point. Also in the player configuration, it has the property that it always returns to the saved point. We review each trigger in detail and they are the same as the 1st section where that doesn´t happen. Have you had a similar experience?
