Most likely you have blank lines in your input file. Use this code:

Code:
awk 'NF {
  sec = $2; fifth = split($5, _fifth, ","); sixth = split($6, _sixth, ",")
  counter = 0; key = $1; flag = $4; sub(/[^ \t*]*/, "")
  dummy = sprintf("%*s", length(key),x)
  for (i=1; i<=sixth; i++) {
    second_third = sec + _sixth[i] FS _fifth[i] + sec + _sixth[i]
    third_second = _fifth[i] + sec + _sixth[i] FS sec + _sixth[i] 
    if (flag == "+") 
      rec = rec ? rec RS dummy OFS second_third : key OFS second_third OFS $0
    else  
      rec_rev = rec_rev ? \
        (++counter == sixth - 1 ? key OFS third_second OFS $0 : dummy OFS third_second ) RS rec_rev : \
        dummy OFS third_second
    }
  print (flag == "+" ? rec : rec_rev)    
 }' OFS='\t' ORS='\n\n' r1.txt

NAME
split - split a file into pieces SYNOPSIS
split [ option ... ] [ file ] DESCRIPTION
Split reads file (standard input by default) and writes it in pieces of 1000 lines per output file. The names of the output files are xaa, xab, and so on to xzz. The options are -n Split into n-line pieces. -e expression File divisions occur at each line that matches a regular expression; see regexp(6). Multiple -e options may appear. If a subex- pression of expression is contained in parentheses (...), the output file name is the portion of the line which matches the subex- pression. -f stem Use stem instead of x in output file names. -s suffix Append suffix to names identified under -e. -x Exclude the matched input line from the output file. -i Ignore case in option -e; force output file names (excluding the suffix) to lower case.
