Yes, the bevel is not set, completely.

You can see in the 1K photos, that you are not reaching the edge.

There is also a “Rail Road Track” stria to the left (on the first Photo) and below a deep 45 degree stria in the center of each photo.
That stria should have been removed at 4K.

With each stone you are getting more of the edge but still not completely.

Re-set the bevel with ink and 1k with a bit of pressure, then re-ink and remove all the ink with the 4K. You bevel should straighten out at about 8K and be a bit straighter with each progression. More magnification will give you a better view of the edge.

I don’t really see a lot of difference in your photos, post 1K, from 8k on the difference should be dramatic, lots more polish and finer stria.
You may want to add a bit of pressure and check the corners of your stones, bevel or round them a bit. Alternating your finishing strokes from straight to heel leading with every other stone will quickly tell you if you are removing the previous grit’s stria.

As said depending on the steel, you may need a bit more pressure and do more laps.
