Custom Post Types

on updating wordpress to 4.7 and plugin to 2.1.3 my other custom post type that i had created from my custom plugin aren’t showing archive pages that i have created using archive-customposttypename.php (eg: archive-station.php) instead its showing wordpress default archive page.

when deactivating restaurant menu plugin these archives pages are showing correctly but on activating this plugin the above problem starts. furthermore this problem wasn’t there before update of wordpress and plugin. it appeared after update
