That might be the case if the plunge started there instead of behind it.

There are a couple unusual things going on there. In general I don't like sharp plunges* so I set my grinder up so that the belt hangs off to one side of the (round edged) platen so that I can grind in a gradual sweep.
As a result of this the edge is going to be much thicker right at the start of the grind, so I cut a notch for ease of sharpening and to keep the secondary bevel from "smearing" upward when applied.
Ignore the dust and dirt, I've been sweeping the shop today.
*Exacerbated by asymetrically ground knives since the plunge is twice as deep.

Here are a couple quick examples from my desk of how production knives handle the same issue.
Ontario's contractors just say "Screw it".
Look how far from the plunge the edge starts.
Kershaw uses an extended choil-to-guard on the Needs Work ( but still has a bit of thickness and edge smear)

Well that is 2 ways to handle it.
Gottcha. Putting in the notch so the final grind for sharpening doesn't run over the edge of the plunge is the most common reason, but I didn't know if you intended another purpose as well since it started further forward than most set for a clean start to final. If sized for the purpose it makes a good wire stripper and helps in breaking cordage or light wire. I assume you set it after the plunge was ground to avoid tearing up your belt?

Most of the time I grind then cut the notch with a round file. There is an alternative method of drilling a hole (that becomes a notch) and and grinding the plunge through it. Mr.Ennis does it this way.
I usually grind primarys edge down so I don't have to worry about snagging a belt or grit spitting on new belts.

Small crescent knife of .095" 15n20 with natural G10FR4 scales this morning.
Roughly 3" of cutting edge.
No sense in making it any prettier since it is going to be sweated on and ride around in a scratchy kydex sheath.
Lot of "bark" striations on this steel from where it was rolled.
This guy was in the same heat treat batch (I've finally started batching some processes), so same steel, cut to Noah's profile but with a high right handed grind.

We haven't heard from Sam in some time and we've been trying all methods to contact him to help resolve this problem with members who've sent money to him for knives.
In the meantime he's been removed from THR staff.
