Hello,
It seems you are unable to see the "sharepoint resource" in local selections. You can follow the steps provided in the following technote and verify if it helps:

In case the above does not correspond to your problem or if it does not help you, do write back to the forums.
However if we do not receive your update within two business days, this post would be marked ‘assumed answered’ and would be moved to ‘answered questions’ pool.
Regards.
