2 Errors when View initially viewed (then errors go away) - Undefined index: combined AND Undefined index: field_names

This is my first D7 site and my first time with Views Dynamic Fields.

When I initially view the View, these two error messages appear at admin/structure/views/view/xx/edit:

    Notice: Undefined index: combined in views_handler_filter_dynamic_fields->pre_query() (line 341 of /sites/all/modules/views_dynamic_fields/handlers/views_handler_filter_dynamic_fields.inc).
    Notice: Undefined index: field_names in views_handler_filter_dynamic_fields->value_form() (line 218 of /sites/all/modules/views_dynamic_fields/handlers/views_handler_filter_dynamic_fields.inc).

Despite the error messages, the View appears to be fine, and accurate.

Then, once the View is displayed, and I click the Apply button for the exposed filters, the error message disappears.

I tried a variety of configurations for the Dynamic Fields filter, but most resulted in the same intial eror, but fine actual performance.

I also get these errors when editing the View:

    Notice: Undefined variable: exposed_input_fields in views_handler_filter_dynamic_fields->value_form() (line 232 of /sites/all/modules/views_dynamic_fields/handlers/views_handler_filter_dynamic_fields.inc).
    Notice: Undefined index: header in template_preprocess_views_view_table() (line 571 of /sites/all/modules/views/theme/theme.inc).
    Notice: Undefined variable: header in include() (line 26 of /sites/all/modules/views/theme/views-view-table.tpl.php).
    Warning: Invalid argument supplied for foreach() in include() (line 26 of /sites/all/modules/views/theme/views-view-table.tpl.php).

This is with the Danland theme. These errors do vary based on the settings.

I disabled Views caching and Flushed Drupal cache many times.

To sum it up, the View appears fine even with the error message displaying, and then the error message disappears when the Apply button is pressed for the exposed filters.
