Yes - user error.
Check and type the thicknesses again.
If you have 11.7 it will round up to 12 if you have the decimal precision turned off.
So you may well have some slightly smaller thicknesses there that you aren't noticing.
See my images.
One is correct but the other I typed 11.7 and 12.7 - they still show as 12 & 13 but total with the correct figure of 169 (actually it would be 168.8 but will round up to 169).
