Not the best example, because there is much randomness, but the first one I found on my Computer.
As you can see, some numbers have a m in the end. So I needed to remove them.
Or one Building, had also underground levels. Didn’t needed them, so I removed it.
And the Buildings where I hadn’t any height, were extruded by random numbers. You can choose the Domain, so it fits to the existing ones.
But you Need nearly always to search the text for Errors. Sometimes there is: “Building:levels:levels is approximate” or something like that.
Hope I could help you.
