Increased Area Of Effect / Concentrated Effect on Righteous Fire

This set up is not working like it should, sometime i have a ridiculously small area on my RF and sometime a big one, and sometime it's like i don't have any support gem at all... and i suppose the increase/decrease on damage isn't applied too. I can also remove RF from my gear and still have the damaging area.

my set up:

- 4links helmet
- Increased Burning Damage/Conc effect/Increased area(20%quality)/RF
- all lvl19/20

I can't figure how to post screenshot so here is some explanations:

1- Only RF -> normal
2- add Conc effect -> no change (not normal)
3- remove Conc effect -> smaller area (not normal)
4- recast RF
5- add Increase area -> no change (not normal)
6- remove Increase area -> bigger area (not normal)
7- recast RF
8- add Conc then Increase area -> smaller area (not normal)
9- remove then add Conc -> bigger area (not normal)
10- remove then add increase -> base area then smaller area (not normal)
11- recast RF
12- add Increase area then Conc -> bigger area (not normal)

etc.

I guess there is something not normal somewhere?

it feels like the gems have their abilities reversed. If you take conc effect out and back in it doubles the aoe not reduced, same thing with increased aoe, it reduces. God job GGG on another great patch, how was missed in beta is beyond me, or getting a quick fix.

Also, if you take out Increased Area your RF area doesn't change. But when you stick it back in, your RF area shrinks massively!

I am also experiencing this in warbands league. Bug report reference #2,827,312,926
