Hello @DestPr
When I try to add for 3 suffix, 3 task are getting created. But when i add a new suffix instead of creating one/new task with the new suffix, the tasks are getting duplicated its taking earlier 3 suffix and also taking the new suffix. .
How/where are you adding the new suffix?
From your screenshots I can't tell what the iterator is iterating over.
But in general if you follow this approach then there won't be doubling up of suffixes: First set a variable, e.g. comma-separated suffixes; iterate over the array you get when splitting the comma-separated string ( split( {variableName} ; ,) ). at that point you will only ever have ONE suffix to append.
