Hm, as a data point, I just created a new base and table and it shows up for me

Thank you for your answer. I tried again. But the “Number” field is still missing. 
 

Depending on where your “number” field is located, could it be that in French it’ called “Numero”?

Hm yeah, the ‘#’ icon indicates that ‘Numero’ is the ‘Number’ type field, so that’s the one you’re looking for

That’s an interesting bug you’ve found!
