Rapid Rig: Modular V3

Hola, owned this product for over a year and now I've been having problems with creating asymmetrical rigs. Right now it will properly create stuff on the left side of the rig, but if I create something on the right side it creates a jumbled mess. I'm working on a rig for a character that has a flail arm and I need to create a chain on the right side but as I said, it doesn't even finish creating the module. Works fine if done as a pair or on the left side. Here's whats being shown in the script log:
