@jeffreyway as @chrizzmeister said, it`s probably cached or smth like that, cause after some time passed it changes to completed. The same thing occurs with series i'm in progress or just completed, it's updates but not instantly, not sure how much time need to pass though. just as an example https://prnt.sc/mxldzf - this course i just finished(zoomed out page just for clarity and show that all markers stays as checked) and so how i see this exact course in Journey section https://prnt.sc/mxlef6 So i suppose at will change to completed after some time, just as was with other cases
I`m kinda curious is completion status of series based on time spend watching videos of this series? Before i bought subscription i watched series called "PHP 7 Up and Running", and now after i got my account i went in these series to mark them as watched and after i clicked in every video "Lesson complete button" the progress bar still says i'm at 0%. There goes more, i started to watch "Journey PHP Skil" with first series called "The PHP Practitioner", some of things there i knew, so i skipped or just run through and after watched all videos of this series it says i'm only 68% of completion and in the Journey section i don't have mark that i completed these series(i'm talking about the same mark u have near the lesson after u press Lesson complete button).
