GZCLP Programming Question

I am in my 5th week of running GZCLP. I am enjoying the program and progressing in all of my lifts, but my bench press is starting to hit the wall. In all of the other lifts, I am able to bang out 4-6 on the AMRAP set, add weight week-to-week without it feeling much heavier than the previous week. But on bench, I have only hit 3 reps on the AMRAP set the past two weeks. I'll likely fail on reps in the next couple of weeks. That's probably the wrong attitude to have, but the weight is starting to feel really heavy compared to the other lifts.

I should note that I ran Greyskull for 8 weeks prior, which was the beginning of my barbell training. I was feeling beat up, so I deloaded one week and then started GZCLP 10% lower then were I left off on Greyskull. I switched to GZCLP because I wanted to bench twice per week every week since my bench press was lagging.

My current program is as follows:

Monday
T1 Squat 5x3+
T2 Bench Press 3x10
T3 Lat Pulldown 3x15
T3 Leg Extensions 3x15
T3 Cable Crunch 3x15

Wednesday
T1 Press
T2 RDL
T3 Lateral Raise
T3 Cable Row
T3 EZ bar curl

Friday
T1 Bench Press
T2 Leg Press
T3 Cable Crossover
T3 Lat Pulldown
T3 Assisted Dips

Saturday
T1 Deadlift
T2 Press
T3 Cable Row
T3 DB Hammer Curl
T3 Ab Wheel

Is there anything that I can add or change to help with my bench press? I was thinking about adding DB incline press to my Wednesday workout and maybe swapping one of the Monday exercises for a triceps exercise, but I don't know, so I'm looking for some guidance.

Or, do I stay with what I am doing, fail on the lift, and progress as the program calls for to push through the plateau?

I should also note my stats and diet:
46 yrs old
5'-9"
183 lb

2650 cal per day
184g protein
88g Fat
278g Carb

Thanks for any input.
