Unable to update the Fields in Robohelp

Hi

I have created a master page and inserted "Title" field in it. And I have created a topic with a title associating this master page. Because of the "Title" field inserted in the master page, the title given to the topic is reflected on the page. But issue is when I tried changing the title of the topic, the change is updated in the TOC but not on the page. The page is still retaining the previous title, which I have given at the time of creating topic. Even when I tried updating the title using "Update Field", it is not updating.

If there is any other way to updating the fields, please do let me know.

Thanks in advance.
