I have upgraded to the paid version 2.2.7 and getting some weird SEF URLs

These new URLs are duplicate but are being made like this for the home page:

/index.php?option=com_frontpage

It is adding the forward slash before the old URL.

1 0 index.php?option=com_frontpage&Itemid=1
2 0 2.html /index.php?option=com_frontpage

This is happening on quite a few other pages, any idea?
