VLOOKUP drops some rows and doesn't populate.
I have a very weird issue with my Numbers for MacOS. Whenever I hold and drag down in my VLOOKUP column to apply the formula to all my students, VLOOKUP gradually omits more and more data from the range. It looks like this - as I go lower in the lookup column, the less source data is being taken.
The lower I go the less data from the right columns is being used (marked pink)
