You probably need coaching. Have you submitted a video upstairs?
You may need to use a "leader set." This is a concept I did not invent, but I am going to introduce when I get back to article writing. You need to force weight onto the bar every week on your bench and press. Essentially the leader set will be one max set between 2-5 reps. You will follow that with 2-3x5 back off sets for your volume.
