Gravity Forms Checkboxes to Lasso

Hello, Awesome plugin!

I’ve mapped out all of my data properly according to this post I’ve found:
http://support.lassocrm.com/hc/en-us/articles/209976413-Integrating-Gravity-Form-with-Lasso

All of my answers are going through fine except my checkboxes.

I tried changing the separators as shown here with no luck:

Any help working through this is appreciated.

Thank you!
