I want to assign a random string to 4 variables in the same WF and I set:

var 1 = Calculate RadomString (5 characters, use letters, use numbers)

var 2 = Calculate RadomString (5 characters, use letters, use numbers)

var 3 = Calculate RadomString (6 characters, use letters, use numbers)

var 4 = Calculate RadomString (6 characters, use letters, use numbers)

What I get is:

var 1 = var 2 = first 5 digits of var 3 = first 5 digits of var 4

var 3 = var 4

This should instead produce 4 different values.

Do you have any suggestion to get 4 different strings? Thx
