VO2 max data - no longer shows to 2 decimal places in csv file?

Hi all

I used to download my VO2 max csv file each day to see the granular change in the VO2 max value, but now it only shows it to a whole number.  I tried changing the data in excel using the "show decimal places" thing in the data section, but there wasn't any to see.

does anyone have any advice?

thanks
