MP5 and Manareg Bonus from Green Dragonscale set are not shown correctly

[Najtan88]

The 2 Set Boni from Green Dragon Mail Set are not shown correctly.

As you can see 10 Mp5 i got from my gear (6 from weapon and 4 from my Ring) but the 3 mp5 from the (2) Bonus is missing.
Also so 15% Manareg (3) bonus ist not shown correctly in Regeneration (While Casting)

Thanks you

(playing Classic Era, no hardcore)
