Numbers does not import CSV files properly
Using Numbers v 3.6.2 under OS X El Capitan v 10.11.6 CSV files are not imported correctly. A file with 8 columns appears in Numbers as two columns with the first containing data from 7 columns and the second containing the data from the remaining column. This does not happen with Numbers v 2.1 which I have on another Mac running OS X v10.6.8
Alright I know one answer would be to always to download to the latter Mac but I am trying to stop using this once all data that I need is available on the other, later, Mac.
If Apple could provide a program that does the job correctly why on earth can't a later version do the same, it's a basic requirement and I don't want to play around trying to sort it out I just want it to work as it ought to.
