</tbody></table></div><div><br></div><div><br></div><div>I expect the reason "some" points rendered on top and not others, is that the slight positional offset would have likely ended up giving the points different altitudes based on the "clamp to ground" positions.</div><div></div><div><br></div><div>There are a number of approaches you can utilise to resolve this issue, depending on your needs.

I tried your file on Google Earth Pro 7.3.4.8248 (64-bit) on
Win10. I get an even stranger result - two of the small circles
appear on top of the big circles, the other two behind.<br>
Both layers are listed as clamp to ground.<br>
