How to delete external break point type ABAP COMMAND

Hi Guys,

I have set an external break point at abap command MESSAGE. I would like to delete it.

Whatever I did does not work. I cannot change it to session break point. I tried to deactivate it, delete all break points....

whenever I set up an external break point in web dynpro, this break point keeps on coming back. I tried to press all buttons in the new and classic debugger but I can't get rid of it. so it stops all the time....

Do you know where the break points are stored or any idea how to get rid of it when I am under WD session?
