Calculate RandomString does not reset if used twice or more in a WF

[gianluca1]

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

For the records: I solved using the plugin Radom String Generator.
Still it would be useful if Bubble fixes the bug to avoid other Bubblers getting in trouble. Thx
