What am I am Doing wrong?

Maybe nothing!

The sharpening file is not supposed to go deep into the gullet. It forms the top plate edge, and the upper part of the side plate edge - those are the parts that do the cutting.

After you have sharpened those edges a few times, you go back and adjust the depth gauges, and free-hand file / shape the gullet to a smooth curve that matches the original profile, removing those 'bumps'. You should not file into the tie straps.

Bottom line: how does the chain cut?

Yes, I agree those bumps/hooks in the gullet need to be removed, the chain will not perform as well as it could or should do.

Also as you have filed with the wrong size file, the angle/s, top plate and side plate will take some filing to get those desired angles back.

It could/will wear a file out just trying to file it back to std angles

I’m going to buy the blue one. I see there is a 7/32 and a 13/64. Which one?

Oregon will say 7/32" for their 3/8 chain.
STIHL will say 13/64" for their 3/8 chain.

You will still need to clean out the gullet occasionally.

That 1/64 won’t make a damn bit of difference. Once you get the hang of it Looking at that first tooth I think you’re on the right track. You just have to get it in your head the end result you’re looking for. I feel like I could show in person better than trying to explain where I think the file should be held

I bought a 2n1 for work because my guys can't sharpen worth a dang in the field. I tried it out the other evening and I definitely like it. I'm not a fan of how the taker is filed so I rounded them over a little. I was impressed enough, I bought a few for Christmas gifts for the people I sharpen chains for at church. I bought the Stihl brand because that is what I can get local, but may buy a few Pferd ones from Amazon for work in 3/8P and .325.

You will be fine now that you are using the right size file....

The 3/8 lo-pro file is definitely way to small for regular 3/8 chain.....

^^^^ This^^^

You can use any file size and make it cut, some just make more sense than the others.
I've even used 1/4" files on 3/8 with decent results.
I've ground 3/8 chain with a wheel intended for .325 with good results. Not ideal, but it works.
Ideally, you want 20% of your file above the side plate give or take a few.
