Error: Call to undefined function acf_local()

Hi I get the following error when trying to export using WP All Export Pro Version 1.5.2

I have Advanced Custom Fields Version 5.8.7 and WordPress 5.3.2 installed.

Fatal error: Uncaught Error: Call to undefined function acf_local() in /public_html/wp-content/plugins/wp-all-export-pro/libraries/XmlExportACF.php:26 Stack trace: #0 /public_html/wp-content/plugins/wp-all-export-pro/libraries/XmlExportEngine.php(545): XmlExportACF->init(Array) #1 /public_html/wp-content/plugins/wp-all-export-pro/libraries/XmlCsvExport.php(812): XmlExportEngine->init_available_data() #2 /public_html/wp-content/plugins/wp-all-export-pro/controllers/admin/export.php(137): XmlCsvExport::auto_genetate_export_fields(Array, Object(WP_Error)) #3 /public_html/wp-content/plugins/wp-all-export-pro/wp-all-export-pro.php(407): PMXE_Admin_Export->index() #4 /public_html/wp-includes/class-wp-hook.php(288): PMXE_Plugin->adminInit(”) #5 /public_html/wp-includes/class-wp-hook.php(312): WP_Hook->apply_filters(NULL, Array) #6 /public_html/wp-includes/plugin.php(478): WP_Hook->do_action(Array) #7 /public_html/wp-admin/admin.php(170): d in /public_html/wp-content/plugins/wp-all-export-pro/libraries/XmlExportACF.php on line 26
