The key lies in the use of the 'index' input, for which the help text reads: 

"Indicates the line within the list where the next insert, replace or delete action will occur. See help for the 'insert', 'delete' and 'replace' inputs for details on how this index is used"

When using of the 'index' input to target where I wanted the specific action to happen, I was able to use the 'insert', 'replace', and 'delete' inputs just fine with your file.
