Plugin not compatible with Gravity Wiz perks

Not sure if there’s anything that can be done about this. Purchased a Premium version of this plugin. I’m on the WordPress version 4.9.8 running Divi theme. GravityForms Version 2.3.3.1. Using GP Nested Forms perk from Gravity Wiz. Unless I deactivate that perk, I can’t even see export options on the form settings screen. Once deactivated, I was able to set an automation, but had to adjust it again before it ran. Second time I tried to save new settings I got Server error 500. Had to delete plugin using FTP client before I was able to get back into my WP Dashboard. I know $7 for this plugin is a very small amount of money to pay, but wanted to post it here so people can make their own decision before the pay.
