You're reading a .tpr file written with a more recent version of GROMACS than the version of trjconv you are using. Because the file formats change as time passes, old code cannot always correctly interpret new data. You should judge either to make a .tpr in the old format, use a file in a different format for -s, or do your analysis with the new code.
