Hello @bleedingsaber,
There are 2 ways.
Using nested replace() functions
{{replace(replace("[[test]]"; "]]"; emptystring); "[["; emptystring)}}
Note: If there are any specific variable is used as input, replace [[test]] with it.
Using Regular Expression
This create more complexity for you to handle expression as well as replace().
Try the first one if that’s not works then come up with your error.
