When a company is associated to a contact and that company has an apostrophe, it will continue to create new wordpress post with a duplicate company name. Don’t know what other punctuations. Don’t know what’s it’s doing on the postmeta side.

Side note, the initial company was auto-created via the contact form.

Steps

1) create/edit new contact and enter the company name (ex: O’brian Inc) . A wordpress post of the company is created.
2) create/edit another contact and enter the same company name (ex: O’brian Inc) or select the company from the list, and it will create another wordpress post with the same name company name.

This does not happen when you don’t use an apostrophe.
