Your cables are probably fine. I made a thread on the other 9th gen Civic forum regarding this issue, and I think more and more people are experiencing what I did, or to a lesser degree, and not noticing.
So my BB SS was the first mod I did to my car almost a year ago. I remember at the time liking it, and had good luck with it. Well little by little my driving experience started to suffer. Fast forward to probably 3 months ago, my shifting was so bad, I just couldn't figure out what was going on. Shifting was sloppy, inconsistent, and notchy. Sometimes I would grind a gear shifting very slow and pushing the clutch all the way in. I have done everything short of the CDV delete on this car (Hybrid Racing EM1 CMC, MTEC springs, Hybrid Racing cable bushings, TWM base bushings, BC SS). Here is the thread I started on the other forum:
So I have been really trying to clean up some sloppiness in my shifter feel. My shifts felt inconsistent, sloppy, and notchy. I installed a Buddy Club SS as my fist mod on the car, almost a year ago. Since then I have done MTEC springs, TWM base bushings, Hybrid Racing cable bushings, and a Hybrid Racing EM1 CMC. I have tried a few different fluids for the tranny as well (right now I am running a Torco MTF/RTF mix). Still frustrated with what I would call a "dead zone" in the shifter. I could wiggle the shift knob and there was a significant amount of slop in the short shifter its self. Well curiosity got the best of me and I decided to tear it apart to look into it. I kept my stock shifter (I have kept every stock part I have removed, glad I did), and upon looking at that, I noticed that there is no play in the shifter its self, it is very solid. Here is a video I took of the wiggle I am talking about with the BC SS:

This is certainly not normal. There is a lock ring on the top of the cage so you can remove the lever, and that was locked. On the bottom of the assembly, I could see that the plastic that supports the bottom of the pivot ball was broken. I have no idea how long it has been like this, but I have been chasing dragons forever trying to get rid of this. The car only has 11,000 miles so I figured it wasn't cables. I installed the stock shifter and what a WORLD of difference! Absolutely zero play, very precise and predictable shifting, and each gear feels the same. I am not sure if I should contact BC on this issue.
@team3d do you think it is worth giving them a call? I don't think it has been a year since I bought one from you but maybe it has. Here is a picture of one of the broken tabs I was able to find:
You can see me effortlessly wiggling the lever back and fourth. Beyond the dead zone, you can feel the MTEC springs start to kick in. Once I took the interior panels off the damage was obvious. Here you can see the pivot ball of the shift lever, and how much play it has inside the cage:
