[solve] Not list opportunity in related list

[joebordes]

Well, you actually found an error that we get directly from vtiger, I thought we didn't have any of those left :-)

With this change, the potentials related list on contacts will show all related potentials, directly, related to the contact's account and related to the related list of potentials.

I'd say that you have added the related list using the layout editor. If that is the case you will have to recover the one that was there before because this is a special relation inherited from sugar crm (!)
