Pocket Recognition in 2D Pocket not working when identifying holes cut through sheet metal into flat pattern

Edit: Updated title to Pocket Recognition instead of "Hole Recognition"

The Pocket Recognition in Manufacturing > 2D Pocket doesn't pick up all of the holes a lot of the time for me.

The holes in the sheet metal as shown below were cut from a sketch on one side of the sheet metal through to the other side when folded up. I applied Rectangle Pattern to one hole using the Extrude feature to make the 3 in a row (6 total including both sides). I used the Mirror on the another hole's Extrude feature to create the 2 (4 total) other holes.

I would expect if my setup is based off the Flat Pattern that these holes would be recognised by the 2d pocket tool. However they are not. I only find it an issue with extruding through multiple folded metal pieces (of the same sheet metal part) and sometimes when performing actions such as patterns, mirrors, etc.

My best guess is that the pocket recognition needs to be told what surface to check or something. I am sure it's a small step I am missing but I can't find the option and have been looking for a solution for a long time. I expect it is a missed step because I can't seem to find the same issues from others in the forums.

I have attached the sample I made up to demonstrate this. Any help would be appreciated.

Here is the sketch of the 2 holes I extruded and either patterned or mirrored:

This is the type of extrudes I am doing:

And here is it with the timeline current and the sketch visible. Please note the sketch only has 2 circles drawn. The extra holes are from pattern and mirror features of the extrudes applied to the sketch circles.

Flat pattern confirmed up to date.

Not using Drill? Will find all holes per size.

2d pocket you need to select each outline.

Might help

I thought the Drill functionality was just for drilling the size of the bit through material. I am not sure how to make it clear the entire hole. I will have a look into this more. This example doesn't include slots and different size holes which I should have included as that is closer to a real world situation. I don't actually make the demo part for anything it was just a demo.

I will do some research on it but I am not sure this is the solution I am looking for. I really appreciate your help and I will put some time into learning what the drill function is capable of.

It just seems to be doing a plunge into the middle point of the holes but not clearing more than the wide of the bit.

I also tried creating a slot in one side, extruding it to the other side and creating a pattern to make it 3 on each side. The pocket recognition works on the slots on both sides and the holes only on one side.
