Unfortunately we were not able to reproduce the issue on our side. The only scenario in our tests when there aren't any stored procedures in Update From Database -> Select Changes window, is when the checked stored procedures are already added.
Could you verify that you are not trying to add stored procedures that are already in the Domain Model? You can see the added stored procedures from the Model Schema Explorer in the Stored Procedures and Functions section.
If this is not the case, could you try to reproduce the wrong behavior in these two scenarios:
1) In another project with the same database.
2) In another project with a different database.
If you reproduce the problem and you can send a sample application that demonstrates it, could you let us know, so that we can make the attachments available in this thread and you can send it over for analysis?
I am looking forward to hearing from you.
