In the spirit of justice since both of them have their issues resolved they should do the needful by removing the tag since leaving them at this point make their feedback wrong since the problem mentioned is already solved by the trustdice team.
And regardless if the members are on DT or not a tag is a tag anyways and once given for a specific reseason it should be reviewed from time to time if and when the issues are resolved.
Sometimes they are more concerned about the behavior of the casino more than the result itself. A casino may have solved the case but how they reacted in a particular situation can draw criticism or appreciation from the community. I feel a neutral tag is warranted in such cases that are solved but you have a strong opinion based on that case.
And as Solosanz mentioned, it's a open forum and anyone is free to give any feedback although DT are more careful because their feedback carry more weight. It would be ideal to solve the problem via direct communication with the DT members and explaining to them.
