Robert,

Did you restart the LDM after changing your request lin, or
could you have another request line in effect also?

The trailing "*" character is redundant, so you should remove that,
and otherwise the pattern with: 
MT.gfs_CY.(00|12|18).*DF.gr1/fh.(0[0-9][0-9][02468]).*/(UGRD|VGRD|HGT|RH|TMP|APCP|ACPCP|PRES|ABSV)/
should restrict what you are getting to matching that subset.
