Issues saving multiple SVG files from 1 Illustrator file (multiple artboards)

Hello!

I have an Illustrator file with 10 artboards.

Up until yesterday I have been happily saving (file - save as - svg) my work as SVGs and always check the "Use Artboards" option. This gives me 10 individual SVGs. However now I am finding overnight that has broken.

Now when I save, I get 10 indiviaul SVG files but when I open each svg file there are 10 artboards inside the file instead of just 1 artboard per file.

Does anyone know what is happening? How I can fix it?

Note: Just updated to the new version (27.1.1) thinking issue was the old version and still having the same issue

Operating system MacOS Monterey Version 12.5.1

Adobe Illustrator Version 27.1.1
