My TIFF file is opening tall and narrow

I have have several scans that were saved as compressed TIFF that used to be roughly the shape of a letter-size piece of paper. Now when I open them, they're displaying squashed, tall and narrow. Other scans made in the same group, at the same time, saved the same way, don't show this. The ones that are not squashed say "(Gray/8)" in the title bar. The ones that are squashed say "(Gray/8) [scaled]" in the title bar. The preview in the Open dialog shows the correct shape.

I've never seen this before. Is this "scaling" something I can turn off?
