Chain not sliding inside the gauge but riding on the top of nose sprocket teeth.

[NAKATA]

Good evening Gents!

I need your expert opinion on the following matter:

Is this gap between the bar`s gauge and the chain on the nose normal or the chain has to be touching and sliding on the gauge?

My opinion is that the chain has to slide on the gauge and not riding on the sprocket teeth as it create too much stress on the sprocket teeth bearing.

See photos bellow!

The drive links fold around the teeth at the nose and if you see sparks it is because it is rubbing. If the first picture has sort of rounded tips after the chain is removed for viewing it is the correct one for 3/8lp but if the tips are kind of pointy that tip is for full sized 3/8.
