Guardian Rank - Health Increase

I am not sure what is going on or if it just isn’t supposed to actually increase the displayed health number. But I have sank multiple points into increasing my characters health. I want to say I have the value up to over +6 or 7 % at this point. And my health seems to be stuck at about 8100ish. The last 3 GR points spent went towards increasing my total health and it has not gone up.

Is this something that happens behind the scenes? Or is there a bug?
