So my question is, are there any known issues (such as with the debouncing) that I can easily remedy myself?

As a first step, I’d recommend trying the built-in test mode, to see if it shows an error for the mentioned key. See this post for a short HOWTO:

Kaleidoscope-Model01-TestMode documentation?

It’s mostly useful to detect hardware issues, but here’s how to use it: press PROG, LED and left Fn together at the same time to enter the test mode. First, it will test the LEDs by going through a few colors (waiting for any keypress in between): red, green, blue, then white. It will follow that with 1000 cycles of rainbow. Then it enters the matrix test mode. In this mode, when you press a key, it will aggressively check for chatter (by reducing debounce time significantly). By default, all …

Then, send a mail to help@keyboard.io, with your original post here, and the test mode results. They’ll walk you through the possible options. Emailing that address is important - especially if the key was dead on arrival - so they can keep a tally of faults.
