New update causes error

I just want to inform you that after updating the plugin (Version: 1.1.1) I get the following error when I visit my group’s page.
” Notice: Undefined index: display in http://www.mysite.com\wp-content\plugins\bp-create-group-type\public\class-bp-add-group-types-public.php on line 229 ”

Please verify.
