Description of problem:

When clicking the refresh button on a dynamic dialog, the value appears to load fine in the UI, however the value is never accepted, and is showing as nil in the dialog_parser method:

[----] I, [2019-06-06T10:36:37.149619 #20839:d1f128]  INFO -- : Q-task_id([r1000000000010_service_template_provision_task_1000000000010]) <AEMethod dialog_parser> dialog_options: {"dialog_dummy_text_box_1"=>nil, "dialog_dummy_text_box_2"=>"No worries Mate!", "request"=>"clone_to_service", :service_action=>"Provision", "Service::Service"=>1000000000010}

Above there are 2 dynamic dialogs, both with the exact same setup and automate method populating the values.  "dialog_dummy_text_box_1" was refreshed, and shows the value nil, while "dialog_dummy_text_box_2" was not refreshed, and shows the "No worries Mate!" value.  Note, these 2 dialogs have "Load on Init" enabled.  I tried it with "Load on Init" disabled, and we still see the refresh is sending a nil value for "dialog_dummy_text_box_1":
