Spotlight

I dunno why but when i choose to spotlighting someone more than 1, zoom app auto remove all of my spotlight although i usually tap ADD SPOTLIGHT instead REMOVE OR REPLACE. Its kinda annoying, its like i am gambling at my spotlight to be success or not. If i success i can spotlight 2 people, but when i want to spotlight > 2 people, i back to gambling state:
50%: 3 person spotlighted
50%: all spotlight were removed

Pls help me what should i do or the zoom it self bugging?
