Why my threshold color does not work correctly

According to attach pic my value is 14 GB but I fixed threshold to show :

0-17G = red and show green for more than 17G
As you can see my output is 14G so should should change to red but is is showing green . Why ?

What should I correct ?

Hey there! I got the same issue, did you figure it out?

Edit:
After some research, I discovered that thresholds are applied to the raw value, not the converted one. In my case the value was in bytes, so I divided it by 1073741824 to get the GiB and then the thresholds started working for me. Hope this helps.
