Account error after being ejected from Admin role

Hi all,
I have encountered an issue. After my account is removed by another Admin, I can’t access to Automation feature. And from some boards we have been using, when I tried to create new items, they were logged and displayed under another member’s name of my company, not me. I don’t know what happened to my account. Before being assigned as an Admin, I still was able to use the Automation normally.
I have found out another problem this my account. I have a board that I’m already its owner, but when I open the Automation in that board, a notification says “Automation Center is available to board owners only”. Those things are really annoying me several days round that I can’t use this great feature. Please fix those things for me soon.
Thank you.
