CMB2 Conditional

I’ve been at this since 3 days but no avail I’m trying to implement Conditionals via one of these two plugins on a fresh wp install :
https://github.com/jcchavezs/cmb2-conditionals
https://github.com/awran5/CMB2-conditional-logic

my CMb2 directory is [theme url]/function/cmb2/
when I try to load up the example of the first one on a custom post multicheck stops working for the conditional
the only thing i see as an error is this in the console on both plugin
