This looks like a rounding error in the calculation of the bounds. Ifyou change the number of levels to 50 a suitable upper bound is found.

 
shade/lev=50 co_emac

works as expected. The maximum level appears to be calculated as 1.85E-7rather than 1.90E-7. The symbol LEV_MAX should report this but I see itas "0" which is rather useless.

 
 
LEV_MIN = "0"
LEV_MAX = "0"
LEV_NUM = "29"
LEV_DEL = "0"

My guess is that there is a problem with the number of significantfigures required and the precision available in the 1E-7 neighbourhood.
