Course completion progress not correct


I have completed the course AI for managers. but it is showing %completion as 99 . also two topic are not scored 100%, but i dont see anything pending in that two sections.
please check.

when i will get the completion certificate?


I have also a similar bug on my course index for Machine Learning Specialization course. Some of the topics which I have already completed aren’t listed on my profile (Topics completed) and the new topics which I am finishing show incomplete progress bar status (96% complete, 99%complete).
