Tournament types error

Hello

I have just installed on clean WordPress Arcane theme, activated most of the plugins including additional tournaments and when I have turned on Tournament types (all 4) in Theme Options I got an error:

supplied for foreach() in D:\xampp\htdocs\arcane\wp-content\themes\arcane\addons\tournaments\main.php on line 273

It is visible on every single page:

as well after I save Tournament options they remain unticked:

There is no modification to the WordPress or theme/plugins at all, just clean install.
The error is gone when I “Restore Options Default”, tho this prevents me from using theme tournaments.
