Hi Frances,
it looks like a problem related to the cache of GWT. Probably Google fetch and crawled the site when the Joomla SEF was turned off and now it continue to show those results.
Currently both your sitemaps and site is working on using SEF links:
http://ticgums.com/index.php?option=com_jmap&view=sitemap&format=xml http://www.ticgums.com/index.php?option=com_jmap&view=sitemap&format=xml
First of all you should choose a preferred domain in GWT, with 'www'
http://www.ticgums.com/ or without 'www'
http://ticgums.com
After that submit the sitemap and do the rest only for the preferred domain that you chosen. If Google still uses the cached sitemap with non-SEF links, submit an alternative link and it will force Google to refresh, for example:
http://www.ticgums.com/index.php?option=com_jmap&view=sitemap&format=xml&v=2
There is also a parameter in the JSitemap configuration to enable random links that you can turn on at this purpose.
best regards,
John
