Errors when open more than 1 file

[Ivan Toman]

Hi!

Does anybody know what could cause these errors below. I calculating
precipitation sum over forecasted period by opening all ctl files and
summing like this

'd apcpsfc.1 + apcpsfc.2 + apcpsfc.3 +... '

Unfortunately, very often get error like this:

Data Request Error: Invalid grid coordinates
  World coordinates convert to non-integer grid coordinates
    Variable = apcpsfc.2  Dimension = 3
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = apcpsfc.2


When I try to load files manually and look what happen, I found that
problem should be somwhere here; please look:

But, it is not problem with gfs.t00z.pgrb2f48.noaa_g2_rc_ci.grib1.ctl
file, I think. Because of:
