OK, where to begin. The work isn't mine, so I have some speculation here. The work was by a client. I believe he used a stock title block from 2019.
I did a Save-As and the file name now fits in the boundaries. I did have to 'edit' the title block for the TB to find the change. That seems like a bug, It should know. In any event, the title block has not moved.
I was just able to edit the title block Layout and move the title block. That fixed the problem. I had tried that previously, but the move did not work.
In 2019, the placement of the title block geometry no longer as it did before, with he lower right point attaching to the border object?
I can understand using one Locus, see above, if I want the TB to float away from the border, but I'm not sure why two would be required.
