That looks pretty normal for a planetary mixer and 62%. You can either mix it by hand first and them dump it in there for kneading, or lift the dough up once in a while to avoid it getting stuck like that.
Your speed also seems quite high. I would try less speed. As for how long to knead, it's difficult to say, so you'll have to do some testing. Somewhere between 4-10 minutes maybe, but it greatly depends on the speed.
Half an hour of aggressive spinning in that machine? Are you trying to kill the dough?
Planetary mixers are unfortunately not that well equipped for kneading a dough, as you now have first hand experience with. The issue is typically that it gets stuck to the hook and is just riding around, but I can get it to knead somewhat okay on mine, I just have to help it mix properly first.
