If you are new to doing heavy 3s and singles, you might be gaining skill at them, as well as growing new muscle.
At some point, the gains for all rep ranges ought to be about even, as you'll only set PRs due to new muscle growth.
I’ve been doing the program for a number of cycles now. It’s based on a three-week cycle with the 1st week sets of 5 reps for the heavy days, the second week sets of 3 and the last week heavy singles. What I’ve noticed is that my gains for the 1st week sets of 5 reps are increasing albeit very slowly. However my gains on the second and third weeks of the program are going up quite nicely. Every week I am setting PRs but much more so on the 2nd and 3rd weeks than the 1st. Is this normal for this program? Or is some adjustment needed. I’m thinking not as I don’t want to mess with success but needed to ask.

I'm not clear about what you mean exactly. Are you failing reps on the 5's weeks or just feeling that you're struggling harder? If you can keep adding weight to the 5's week every cycle, do so.
I am new to sets of 3 and 1.
I am able to add weight with all the sets however I've noticed that for sets of five I can add maybe one and possibly two pounds where with the sets of 3 and 1 I've been able to add more like 2 and even 3 pounds as each cycle comes around. So the rate of increase is greater with the sets of 3 and 1.
Sooner or later you will start missing reps so just hold the weight there for that week until you do make the reps.
