I have deleted your duplicate post in another forum. Please post once and in the correct forum - which you have done with this post.
When you start from the standard template for your country, there should be NO library errors - no missing, no duplicates. Verify that that is the case.
To have 3,452 objects 'not found' is pretty bizarre. If you load this 11 project with just the same libraries used in 11, do you have any error messages?
You should NOT be loading every library that you have! How about two screenshots: one of the libraries listed as being loaded by library manager, and another showing part of the error report, with the list of 'missing objects' expanded to show the names of some of them.
This 'upgrade for archicad select' must be a country specific library - so somebody from Australia will have to address that...
