From post 4 you show the below output which is incorrect and should be "/home/eric/.local/share/Trash/". What happened when you highlighted a file and did Shift+Delete?

rm -rf ~/.local/Trash/* and the files are still there
I don't know why you have a duplicate path or how that happened, shown below and referred to by oldfred.

/home/eric/.local/share/Trash/files/3962403877/Old1/.local/share/Trash/files/.eteks/sweethome3d
