Anyone else getting an error when RMB the Importer Mapping table?

[OmniZ3D]

# Traceback (most recent call last):
#   File "C:/Users/jbarnidge/Documents/maya/2019/scripts\kiko\ui\datatree.py", line 288, in _show_menu

btw, Great Tool! Very performant, slick GUI, and the options are presented in a clean, organized way...much more intuitive than other GUI and tools i've seen and used.
Nice work!
