First off they do not include the plugin - you have to search for it on the website rather than them including in the email you receive with the link to the component. I am using Joomla 2.5 - I installed both the plugin and the component. When editing the component options - I remove the additional form fields below (mobile. phone, comments, company, ect.) I then click close and save - however the options re-appear both on the front and back end. I also cannot remove the option of "required" for each from filed.
Thank you for the feedback, I am sorry you had to search for the plugin in the website. I accept your suggestion.
Regarding component fields, there are many clients who have downloaded and installed component and plugin works without issues. Your issue may be due to installation or other issues.
You should have communicated to support first before leaving such feedbacks.
Can you please create a support ticket in case issue still exists. I will be happy to help you out.
