Ai Mai Mi just came out, so I got screenshots to demonstrate as I reproduced it, just in case they're useful (thanks for passing it along!)
This really comes down to a matter of timing. For this particular series each episode is 3 minutes long which can lead to more problems than others. The site is not told what second you are at every second because that would be ridiculous, but it doesn't just say beginning and end either because then it couldn't let you continue where you left off. Instead it reports it every ~30 seconds (actual time varies) and then it changes to ~60 seconds. Using Ai Mai Mi as an example, it reports your time at 30 s, 60 s, 120 s, and finally at 180 s. That last one just happens to coincide with the end of the show. If the episode ends and it does not tell the website the time at 180 s then it still thinks the farthest you have watched is 120 s or the 2 minute mark, not far enough to count as having finished the episode.
I watched all of the episodes in order to see if I could reproduce the problem myself. Only once did it happen, but I think that was more a problem with my slow internet. If I had to suggest an easy fix, I would say add one second to the end of each episode. That way they don't have to change any of the video player's code that might affect other series. Regardless, it might take some time to fix.
Does it happen consistently with you or only sometimes? Are you running any other programs at the same time that are using any network resources?
