 * While designing a page with elementor, I am seeing an error with one of the elements.
   I don’t know how can I resolve this one. I have tried adding the column numbers
   for each device but I still see this error.
 * “Warning: Undefined array key “columns_mobile” in /Users/aveendoshi/Local Sites/
   unikmetal/app/public/wp-content/plugins/bdthemes-element-pack/modules/advanced-
   image-gallery/widgets/advanced-image-gallery.php on line 1862″
 * And
 * “Warning: Undefined array key “columns_tablet” in /Users/aveendoshi/Local Sites/
   unikmetal/app/public/wp-content/plugins/bdthemes-element-pack/modules/advanced-
   image-gallery/widgets/advanced-image-gallery.php on line 1863″
 * What does this mean and how can I resolve it?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwarning-undefined-array-key-3%2F%3Foutput_format%3Dmd&locale=en_US)
