Error after cfdb7_filter_before_save filter

I applied cfdb7_filter_before_save filter for some fields in my contact form. After that I created a new record in form. Now when I open this form in CFDB7 I see following issue:

Warning: Invalid argument supplied for foreach() in /home/.sites/963/site4137198/web/wp-content/plugins/contact-form-cfdb7/inc/admin-subpage.php on line 251 Warning: Invalid argument supplied for foreach() in /home/.sites/963/site4137198/web/wp-content/plugins/contact-form-cfdb7/inc/admin-subpage.php on line 256 Warning: Invalid argument supplied for foreach() in /home/.sites/963/site4137198/web/wp-content/plugins/contact-form-cfdb7/inc/admin-subpage.php on line 251 Warning: Invalid argument supplied for foreach() in /home/.sites/963/site4137198/web/wp-content/plugins/contact-form-cfdb7/inc/admin-subpage.php on line 251 Warning: Invalid argument supplied for foreach() in /home/.sites/963/site4137198/web/wp-content/plugins/contact-form-cfdb7/inc/admin-subpage.php on line 251 Warning: Invalid argument supplied for foreach() in /home/.sites/963/site4137198/web/wp-content/plugins/contact-form-cfdb7/inc/admin-subpage.php on line 251 Warning: Invalid argument supplied for foreach() in /home/.sites/963/site4137198/web/wp-content/plugins/contact-form-cfdb7/inc/admin-subpage.php on line 251

Also how can I change order of columns? I have 10 fields, but only 5 of them are showing. I want to change their order to see fields that I need.

Thank you!
