Bug with New Dark Side Vision Rey and SLKR during ult

Hello I found what I believe is to be a bug that occurs with an interaction between Dark Side Vision Rey and Supreme Leader Kylo Ren(SLKR) during his ultimate ability. While he is in ultimate, his siphon stacks are doubled, but when Rey uses Malevolent Lineage against an enemy team with 5 people on it, SLKR only gained 25 siphon. I believe this should have been doubled as written in the abilities. When SLKR gains siphon stacks while using his ultimate ability, they are doubled automatically, but Dark Side's given siphon stacks did not double. When SLKR left his ultimate stance, the siphon stacks that Rey gave to him actually reduced by half. In the screenshot, you can see that SLKR has 52 siphon stacks. Which should be impossible with current abilities in the game. 

Luckily this didn't seem to affect my chances of winning the battle, but it still is an interesting example of how the ability is broken.

If necessary, I was on the PC client and my ally code is 933-956-352
