Is This A BUG?! | Editor Utility SpinBoxes Events Not Working

So, I have an editor utility widget with three spinboxes, we can call them A, B, C. Each spinbox is a duplicate of A. Each spinbox has an event set to OnValueChanged. The event that each has says to print a message to the screen. However, only A works as intended. B and C only run the event on commit. Any thoughts or is this legit bug?
