System Bug

I don't know if any other students have brought this up but when you go through the lessons, like Fundamentals 1, which I completed and also Fundamentals 2, and also Blues 1, it seems the progress bar that is built into the system always stops at 83% completed. Every time I have watched the last lesson in a chapter, it shows 83% completed even after I have watched the conclusion. I have to click the I'm done, click on whatever lesson it is, and watch it a second time in order to make the progress register 100%. Then I am able to click the I'm done twice to record the progress. Is this a simple bug in the system that can be fixed? Anyone else see the same thing?

Try going back through the entire lesson to see if you missed a "finish or complete".
