Widget configuration error in combination with Beaver Builder

[Arn van der Pluijm]

Hi,

I am using beaver builder (https://www.wpbeaverbuilder.com) with this plugin.
Adding the subscription widget is working, but when you try to configure it, it gives an error (in the console):
Error: Syntax error, unrecognized expression: #fl-field-widget-sendgrid_nlvx_widget type=" on line 2 of https://academy.haagsemakers.nl/wp-includes/js/jquery/jquery.js?ver=1.12.4.

Do you have any ideas on how to fix this?
