constant wcs3_admin_js undefined

Hello,

After The installation when I come back to plugins page, I had this error:
Use of undefined constant wcs3_admin_js - assumed 'wcs3_admin_js' in wp-content/plugins/weekly-class-schedule/includes/wcs3_admin.php on line 20

And I’m not sur it’s a bug but Classes/Instructors and locations is in the main menu. If it’s not a bug, it’s awful!

is anybody see that awfull like me?

I stay in version 2…

Great job
