An issue with venue

I can’t add any new venues anymore, and the option “add a new venue” doesn’t appear anywhere.

I’m fairly new at this and run the plugin in German, … so please excuse my linguistic deficiencies:

On the page to edit an existing venue I get this error message:

Warning: Missing argument 2 for SP_Admin_Taxonomies::edit_venue_fields() in /homepages/3/d518396843/htdocs/app518396989/wp-content/plugins/sportspress/includes/admin/class-sp-admin-taxonomies.php on line 77

The code line reads as follows:

public function edit_venue_fields( $term, $taxonomy ) {

Does this help at all to solve this problem?
