Strange URL for Uddeim

Guys

JUst noticed a strange URL construction for Uddeim and wondering how to fix it.

First of all everything works fine.

My menu item points correctly to the Uddeim component with inbox as the selector.

However, on the front end, when you click the MENU item, the URL is

mysite.co.uk/index.php/en/ com-simplecalendar-submenu-statuses/email

It makes no sense, all the Uddeim urls have that in them. I had simplecalendar installed but it is unpublished and not used at all.

Any ideas how to fix this? (see enclosed screenshots)

Thanks

Cliff
