Ive noticed that there is some bug with "likes" in the video section. When you click the like it always becomes red and stay red forever when you scroll the list of videos in the training page. But recently I noticed that all the "likes", which I had already clicked at, lost their red colour. Can you check this please? 

I just used to mark this way videos I have seen, so its quite annoying not to know if I already watched one, cause it lost their colour mark. Thanks in advance!
