Scanner Format No Legal Size

Have a scanner with model HP LaserJet MFP M426fdw (Twain and Wia). Was about to use it for Desktop Apps but in the Scanner Settings, there's no option for "Legal" in the Format section.

Note that we also have the necessary printer drivers installed (the ones from DVD drivers that comes with the printer) and have tried Local Scanning and there's an option for Legal size there.

Any way to fix this?
