Editor broken after update plugin to version 1.8.4

Greeting.
After updating the Gamipress plugin to version 1.8.4, my editor crashed and I got this error:

I think I know what the problem is. When I renamed this file CMB2_hookup.php to CMB2_Hookup.php the editor started working normally and I didn’t get that error anymore.
The file is located: gamipress / libraries / cmb2 / includes / CMB2_hookup.php.
Can you guys check and fix it?
