thank you for your post.
1. Hm, sounds crazy! Not sure what went wrong here, I think there was a problem with the demo content import or something else. We use only WordPress core functions for the real estate categories. Can you send us the link and a login for the website, then we can check the backend for the problem.
2. Hard to say without seeing the source code. Do you think you can send us ( info @ 7theme. net ) the link to your website? Then we can take a look at the source code and help you to find a solution
3. Yes, you are right, we need to fix this. Unfortunately you are the first person that request this feature, otherwise we added it already. We will provide an update as soon as possible and add a link to the page where the form was sent.
