Always my video off although the video setting is not Off

[theg]

Zoom Ver:5.6.10
Setting: Turn your own Video off when you join. ⇒ No check (It means turn on my video when joining the meeting)

Although I want to turn ON my video always , now default setting turn OFF my video when i join the meeting .
Can not find solution, because my setting is always Video ON 
※Setting: Turn your own Video off when you join. ⇒ No check 

If  I create new room , seems that its should be ok to turn ON my video
But All of meeting i join always turn OFF my video, so lazy to turn ON every time

Do you know how to solve this issue?
