Description:

Each company should only have one company size, but filter allows choosing multiple company sizes

Steps to reproduce:

1. Go go search/all listing
2. choose multiple company sizes as filters
3. Able to choose multiple company sizes

Expected result:

• Unable to choose multiple company sizes, as each company should only fall into one company size category. If allow multiple company sizes selection, companies that fulfil any of the filters should be displayed.
• Similar issue for industry
