Try thinking of each aspect of your form on to your release as it is taking place. If something interrupts, thoughts or deeds, start over. Concentrate on where the arrow WILL go, feel the string at the beginning of the draw and as tension increases through the draw, feel your anchor and allow the string to SLIP from your fingers all the while concentration where the arrow WILL go.
Also try going through your draw sequence and when you hit anchor hold for a second then let down slowly. Don't release the arrow. Do this 10 times and on the 10th draw concentrate on where the arrow WILL go and release.
It seems to me you aren't concentrating on the important stuff while you shoot. Try to eliminate everything else in your vision except where the arrow WILL go.
