Remove duplicates separated by delimiter
First post, been browsing for 3 days and came out with nothing so far.

Code:
M3 C2 V5 D5 HH:FF A1-A2,A5-A6,A1-A2,A1-4 B4-B6,B2-B4,B4-B6,B1-B2

output should be
Code:
M3 C2 V5 D5 HH:FF A1-A2,A5-A6,A1-A4 B2-B4,B4-B6,B1-B2

On col 6 and 7 there are strings in form of Ax-Ax and Bx-Bx respectively. Each string are separated by a comma ",".

How can i remove strings that are duplicates across col 6 and col 7.
For e.g if A1-A2,A1-A2 are present on col 6, i want to keep only one.

Code:
awk '{ while(++i<=NF) printf (!a[$i]++) ? $i FS : ","; i=split("",a); print ""}' data

Saw a question like mine on SO , but im stuck.

What am i doing wrong ?

Code:
awk ' 
BEGIN { FS="\t" } ;
{
  split($6, valueArray,",");
  j=0;
  for (i in valueArray) 
  { 
    if (!( valueArray[i] in duplicateArray))
    {
      duplicateArray[j] = valueArray[i];
      j++;
    }
  };
  printf $1 "\t";
  for (j in duplicateArray) 
  {
    if (duplicateArray[j]) {
      printf duplicateArray[j] ",";
    }
  }
  printf "\t";
  print $8

}'

After many failed attempts i came out with the solution of breaking the delimiters to remove duplicate fields across each row, only to realize that I need to regroup all As under col 6 and Bs under col 7. Back to square 1 !

So , the solution for me would be to remove duplicates separated by delimiter in a column. Tried a Perl approach but in vain.

Thank you for your help

*Update
Please note that in this given example, Col 6 and Col 7 are not sorted
