New Throttle Body, Cables Too Short?

In my build up to a supercharger I purchased a 62mm throttle body from Boosted Tech. I have it installed and my idle is now at 1500rpm. I am using the original idle air control sensor and my vaccum tubles look good, no leaks or cracks.

Playing around with throttlebody, I noticed that there is a gap of around 1/8 inch between the butterfly and the screw that I believe it should rest on when the valve is closed. It appears that my cables are so tight, the butterfly valve does not close all the way. If I disconnect my cables, the butterfly comes to rest on the screw and my idle goes back to normal, which is around 750rpm.

Is this a thing that happens? Can the cables be adjusted? My youtube searches are coming up empty on if these cables can be adjusted on a TJ.

Below are pictures of the gap I mentioned with the cables in connected (picture #1). And then, with no gap and normal idle rpm with the cables removed (picture #2). I only have the two cables as shown in picture #3 which I took before I swapped out the TB.

Fixed... sooooo the person I bought this wrangler from installed a CAI and throttle body spacer who knows how long ago. Knowing the spacer is useless, I threw it away when I swapped the throttle body for my new one. I just dug through the trash from two days ago and found the spacer, cleaned it, and put it back on. Now the butterfly valve closes fully and it idles normally. Not sure what was done to the cables when the spacer was installed originally but it appears that I cannot go back to stock...
