Hi sjohn:

 

The thermodynamic database has a strict format with regards to what items are in what columns.  I don't think the numbers matter so long as the required information is in the right columns.

It looks like the last digit in the last temperature is too close to the 1 at the end of the first data row, so the temperatures are being truncated.  Can you please attach a sample of your thermo file that contains the problem lines?

Please note that the thermo header also makes a difference - THERMO vs. THERMO ALL.

If temperature ranges are to be specified separately for each specie, the header usually has a temperature range that will apply if none is specified:
