Using joomla external url gives the same result
All is correctly updated and plugin published in correct order.
I found something interesting though. The non sef link in the back end is not the one that I gave you above which appears in the front end.
The backend menu link created for a category is : index.php?option=com_comprofiler&view=pluginclass&plugin=cbgroupjive&action=categories&categories=14&id=14
and the main cat menu link created is : index.php?option=com_comprofiler&view=pluginclass&plugin=cbgroupjive&action=allcategories
If I use the first one for joomla external id, I get the same problem while the GJ links are SEFed under component/
So there is definitely something wrong somewhere.
For now I won't use a link for individual categories, while it would have helped
