Ranger Pet Health Issue

The health listed in the pet's health bar and the health listed in the pet management window aren't displaying the same number. For example, in the screenshot below it shows the pet has 27,845 HP on the health bar but 29,532 HP in the pet window. Kinda minor but still confusing as to which one is the correct amount.

Did some testing and the amount on the pet health bar seems to be the amount the pet has. However, what's in the pet management is probably what it should be since when I trait "Pack Alpha" the health should go up by 1500 due to the 150 boost to Vitality but instead it only goes up by 1415. Further calculations shows that the amount on the pet health bar is 94.285% of what's listed in the pet management window. So if the pet health bar amount is what the pet actually has then our pets don't have the amount of health they should have.
