If you have chattering, that is sadly a problem with the specific switch itself and the software has just been ignoring the issue. I don’t suppose the keyboard you’re using is hotswappable? If it is, just pull and replace those switches. If not, you either need to desolder the bad switches and resolder in replacements or stick with that software. I have had some consistently bad chattering issues with Gateron switches to the point that I completely avoid them as a manufacturer. So if you coincidentally are using switches from them and plan to replace them, I’d look for a different brand of switch.
