Strange issue, all are doubled

Some issue about the sitemap after upgrading to 2.0 from 1.5

1) Email Notifications now send two email for time with the same content (see below)
2) all content are duplicated, in the summary shows (one example for all) 1218 members but in my forum are 609 registered users

It is possible because I've enabled these options from sitemap settings?

If you have vBSEO, include old urls?
When Google spiders the old url's, it gets 301'ed to the new url's so the old url's re removed from Google. Include this option until you note that most old url's have gone from Google.

Yes, that will include the standard vBulletin URLs as well, so you will have twice as many URLs in your sitemaps.

Ok, so what is your suggest?
And why the sistem sends me two email per time?
Sorry this noobs questions but I'm new to vBSEO tool

Do you have two vBSEO Sitemap Scheduled tasks in your list?

Hello,
in my Scheduled tasks:

1) vbseo_sitemap_task
2) vBSEO - Create Google/Yahoo Sitemap
3) vBSEO Update Service

and vbseo_sitemap_task is unchecked

It seems to be fixed by removing old one (vBSEO - Create Google/Yahoo Sitemap), yup the upgrade has create another task.
Thanks

Prior to vBSEO Sitemap 2.0, it didn't automatically create the task, so you had to manually add it. The manually added one should be removed, if you are upgrading from 1.7 or earlier.
