Do you experience this with a specific project or with all of your projects in Archicad 25?
If it's not project specific, try to repair Archicad, it might be possible that not the whole library is available on your computer.
In case of project specific issue, I suggest to migrate project again with its libraries, if you still have the original Archicad 23 project. I believe it should solve the problem. Or, another idea to delete the linked libraries and re-link Archicad 25 library.
