Various Bugs Found – Catch Fullscreen Pro

Hello I really like the theme of this and decided to upgrade to the Pro version. However, I have found it to be very buggy. Below are a list of bugs i have encountered. - When editing a page the font size changes after updating the page. - The image for each page that I have, includes a headed featured image. Before the upgrade it was displayed in a banner top of the page with the menu name overlayed. Now there is no banner and the image appears within the post. Even when going into the Page and enabling the Header Feature Image Options it still does not revert back to how it was. - Page settings seems to change on their own accord. - Also on your site I could not find the support documentation with instructions etc. Can you point me to the right direction. Would like a resolution of these bugs. If these cannot get fixed I assume I am entitled to a full refund.
