cleaning database from unused or deleted wpmudev plugin

Hello
Happy New Year. I hope you all have had a wonderful holiday.
I am building a network for a client who had at some point used CoursePress and MarketPress and am trying to clean up. I have done as much cleaning as I can including the options table, but for some reason, Advanced access manager plugin still shows CoursePress and MarketPress under miscellaneous for setting capabilities. It tells me there are some tables in the database. I have no idea where they are. I need to find a way to clean this up.
Please, can you tell me how I can achieve this?? I don't understand why it is so difficult to remove these data after deactivation and deletion of these plugins.
I would appreciate any help you can give on resolving this issue.
Regards
Sophie
