So basically if the hero you tried to ban does not get banned, it doesn't show anymore. I believe the system considers that hero as banned not sure.
Hey. I believe you are running some old version of DotaPlus or one of its components. can you please come to the Discord so I can check your logs and fix the issue for you? Use this link: https://discord.gg/kG3ZXym
After taking the steps you told me (updating components) everything is working fine now. Thanks
