[Plugin: Page Lists Plus] Invalaid Argument when removing page for page list

Hello,
I installed Pages Lists Plus, and as per the on screen indication it went flawlessly. I activated it, and again, flawless. However when I went to one of the pages I would like to remove, the option is there to remove it, however after un-checking that box and saving I receive the following errors:

Warning: Invalid argument supplied for foreach() in ::WP DIRECTORY::/wp-content/plugins/page-lists-plus/page-lists-plus.php on line 301

Warning: Invalid argument supplied for foreach() in ::WP DIRECTORY::/wp-content/plugins/page-lists-plus/page-lists-plus.php on line 301

Warning: Cannot modify header information – headers already sent by (output started at ::WP DIRECTORY::/wp-content/plugins/page-lists-plus/page-lists-plus.php:301) in ::WP DIRECTORY::/wp-includes/pluggable.php on line 865

I have looked at the specified lines but I am not really following whats going on, so any help would be appreciated.

Thanks!
