[Plugin: Store Pickup by Gizmocode] Function.array errors

I am using this plugin to allow customers to choose a pickup location when they make a purchase. It is pickup only, we do not ship. After you select your pickup location and checkout you get three error messages on the order confirmation page, in place of showing which pickup location you chose. Any help would be appreciated! You can reproduce the errors by signing up on our waiting list (free). Here are the errors:

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home/content/50/10079350/html/PFmeats/wp-content/plugins/codecanyon-4232273-store-pickup-google-maps-woocommerce-wordpress/classes/class-wc-shipping-store-pickup.php on line 1952

Note: this first error has me baffled, because when I look up line 1952 on this file it is blank!

Warning: array_map() [function.array-map]: Argument #2 should be an array in /home/content/50/10079350/html/PFmeats/wp-content/plugins/woocommerce/includes/class-wc-countries.php on line 649

Warning: extract() expects parameter 1 to be array, null given in /home/content/50/10079350/html/PFmeats/wp-content/plugins/woocommerce/includes/class-wc-countries.php on line 651

Note: on these second two errors, I added (array) before $args on lines 649 and 651. That got rid of the errors, but it did not help in adding back the pickup location and operating hours.
