Valuefield Min/max Values Not Honoured?

The valuefield min/max limiters aren’t watched if i set max to 0 and min to a negative value.
This does work with the valuebox but i don’t want to use that one because it is pretty cumbersome to sync two valueboxes with eachother without facing feedback error nightmares and having to crawl through many different hoops using the tostring and tonumber options (I have to change numbers in steps other than 1).
Nevertheless, i can still limit the value myself by checking it in the notifier, but still i consider it a bit clumsy.
