Dear JavierSp,
The note is here to report an error. The error is valid. That is: this waste container is not here.

I don't know the solution, or I would have solved.

To solve, it's good to have notes, so, somebody can go here, and confirm, and delete the waste container.

Please read there. Notes are useful to report errors. Not solutions.

So, since the error is still there, please do not close this (or similar) notes, without a survey.

Thanks for collaboration :D without this note, nobody will check. Thanks.
