Excel formula not updating automatically

It seems that when the data in his worksheet changes, the SUMIF function doesn't automatically update.

He is, however, able to update the formula if he selects it, presses F2 (to jump into edit mode) and then press Enter.

Not sure if its just my computer yet, currently testing the issue with different computers.

He told me the model did not update, so I checked it out.
