Section 5 not Finished

I am very happy with this training, hopefully I can finish all the training provided. I am currently in section 5 and have registered in the forum that had been previously told before the video in section 5 running, then watched the video and have passed the quiz in that section, but why in section 5 I have not received a sign that I have finished and completed section 5 course. the sign that I mean is like a red sign like the following☑️.Thank you in advance.

Thank you, after I explored in more detail about this problem caused by my own mistake for not pressing the complete and continue button. I apologize and thank you once again.
