System on Live is probably tracking to two decimal places (at least), but only displaying one, as a result it's probably rounded up your stat once it's reached a certain point, while on test it's tracking to two decimal places and displaying two, so it's probably showing the stat at it's actual value.
On the right hand side of the animals health bar you should see a small button with an animals head in it, left click will deselect it, so you need to right click it to bring up the tamer menu, but you do need to be close to the animal.
LAG is a major killer atm though, so if your ping is bouncing up and down then trying to get anything to work is a bit of a mare.
