Gravity Perks - Populate Anything 2.0.39

Fixed issue where arrays populated into values would not be converted to strings for non-multi-selectable-choice fields.

Fixed an issue where filtering by a custom datatabase table date field may return empty results.

Fixed issue with gppa_live_merge_tag_valuefilter not using the correct$field_id` parameter if merge tag modifiers are used.
Fixed issue where selected choices of dynamically populated fields could be lost when navigating between form pages.
Updated AJAX request to send request data as JSON to prevent issues with Merge Tag modifiers from interfering with the form data format.
Fixed issue where certain calculations would not work with Populate Anything if formula fields came after the field being calculated.
