Why has my JavaScript course keep telling me it's not completed??

Question

Javascript course keeps saying i have not completed it, when i completed it 7 months ago and have my certificate printed out. Im a bit confused.

Also for some odd reason, i have noticed that the mobile / tablet version is not properly syncing up progress with the desktop web version. Im using android playstore app version and when i arrive home i use website version.

Answer 1

I don't know if this has anything to do with this, but I completed Javascript before the last section, ES6, was added. Now my progress is incomplete due to that addition.
