I think I see your problem. Hundeds of 'mechanics' over the years have done this too..
You are cutting the seal off even with the face of the main cap and It's not pushing it tight all (360 degrees) around the crank.
Here is what to do.
First: If the upper seal is the same as pic #1 leave it as-is.
Second: Now throw away the seal in pic #2 as it will fail as the others did.
Third: Install a new seal in the cap, leaving 1/4" sticking out of it on each side..
Forth: Install the cap using your best guess @ the torque.
Sixth: Remove the cap. You will see that the exposed portions have gone into the block with some 'squashed' between the block/cap.
Seventh: Trim away the 'squashed portions' and re install carefully so the protruding ends go into the upper seal which now is compressed a little.
Eighth: Torque to specs & install oil pan.
Good luck
