Error on dashboard

Hi, after updating to 0.9.97.46.1 version, on the top of my dashboard screen it appears this:

y: ReduxCore\ReduxFramework\ReduxFramework_extension_demolink_image_select::$field_name in /home/harviup5/public_html/wp-content/plugins/accelerated-mobile-pages/includes/options/extensions/demolink_image_select/extension_demolink_image_select.php on line 66

Notice: Undefined property: ReduxCore\ReduxFramework\ReduxFramework_extension_checkbox_hierarchy::$field_name in /home/harviup5/public_html/wp-content/plugins/accelerated-mobile-pages/includes/options/extensions/checkbox_hierarchy/extension_checkbox_hierarchy.php on line 66

The website doesn’t seem to be affected by that but however it doesn’t sound properly to me.

What does it mean? How solve it?
