I am using PT version 1.5.2.344 as well (down loaded yesterday)
No I am not using any translation.
I first tried selecting and deselecting the various columns to display using the File Finder. That worked fine the first time, but now that is broken too - in fact the display of columns is broken in all file display tools. If I select and deselect various columns some of the data shows up in some other column
I suspect that there is some data that PT keeps, either in the registry or some data files that has become corrupt. Under normal circumstances, I would try an uninstall and a re-install, but there is a dire warning that doing this will disable PT :(
