Good day!

GGness here. I just want to find a way to fix this channel chat bug. I've been trying to exit and leave these spam channels highlighted with a circle at the attached file. They all have the same chat name and I can't leave these channels or remove them from my chat. When I click the leave channel it will just transfer me to the next channel. Please help me to remove this useless chat channels. Thank you so much!
