Why is my progression still at 93% while I am done with the HTML5/CSS3 part 1 course

I have gone through the HTML5/CSS3 course. Even though, at the summary and exercise section, a pop up tells me that an error occurred why I am opening the pdf, I have been able to download it. However, I am not sure why I am not getting a 100% completion and it is still at 93%

well there is part 1, 2, and 3 but then there is also the bundle which is it’s own part as well, you have to click on it and click finish lesson. so make sure you scroll through and double check because sometimes they may skip over and not be complete
