Thanks. Do you mean to look at the K2 items and check for ones that have a blank space instead of something listed under Club? If you look at the attached screenshot there are many items that have Club, Year, Status listed as blank but the search doesn't reflect that.
I am not the creator of this website, I've taken it over from another webmaster so any help you can offer would be great.
No, you show me just a text, but real values which are searchable stored in 'Extra Fields' tab.
Also, this extrafields should be configured here - Components -> K2 -> Extra Fields.
Please, try to find 'Club' field there and remove first empty value.
