Question / Help Game capture

[Adobe]

Hello.
I have 3 windows same game.
When i do "Game capture" in Application list i see 3 names:

• [L2]: LineageClassic.ru
• [L2]: LineageClassic.ru
  
• [L2]: LineageClassic.ru

I choosing any name and OBS get capture first windows always.
Try to change "by windows classname" does't work. I thought this windows have some process ID (when i choose "by windows classname")
