Bivin de Lombardía - Some confusion with Richilde van Metz

I believe there may be confusion in this area although it is an area I'm unfamiliar with. The link on the profile for Richilde I de Metz (http://genealogiequebec.info/testphp/info.php?no=169704) did not reflect the correct parentage so I started by correcting the mother's name to Berthe Trier. This may not be correct as I now see that there is another Richilde van Metz profile further down the tree
Daughter of Folmar I, count in Bleisgau and Bertha van Metz (van Trier)
Wife of Dietrich - Thierry I, duc de Haute-Lorraine and Thibauld de Bois-Ferrand (de Bar), herzog so either a section of tree has been (nearly but not identically)duplicated as an earlier generation or the generations are similar with an incorrect link in the about me as noted above in which case it's possible I have made an error changing the mother's name. There are few notes on these profiles so I don't feel comfortable making further alterations. Private User is the curator so I'll leave it to you Myrna.
