Either I am unable to imagine negative consequence - or both of you did not understand me  
` `  
` `  
The data loss will occur precisely in such cases like @ohrenkino examples - if I will not use the first fail safe [i.e. " tta" with a pause]

All in all, based on this

I went with

```auto
$if($eql('TTA',$upper(%_EXTENSION%)),$repl(%TITLE%,' tta',' '),)
$if($eql('TTA',$upper(%_EXTENSION%)),$repl(%TITLE%,' TTA',' '),)
$if($eql('TTA',$lower(%_EXTENSION%)),$repl(%TITLE%,' tta',' '),)
$if($eql('TTA',$lower(%_EXTENSION%)),$repl(%TITLE%,' TTA',' '),)

```

as I failed at adding `The fourth optional parameter enables ignore case (1)` [[Scripting Functions – Mp3tag Documentation](https://docs.mp3tag.de/scripting)]; i.e. those did not work

```auto
$if($eql('TTA',$upper(%_EXTENSION%)),$repl(%TITLE%,' tta',' ',1),)
$if($eql('TTA',$lower(%_EXTENSION%)),$repl(%TITLE%,' tta',' ',1),)

```

and neither did those

```auto
$if($eql('TTA',$upper(%_EXTENSION%)),$repl(%TITLE%,' tta',' '),1)
$if($eql('TTA',$lower(%_EXTENSION%)),$repl(%TITLE%,' tta',' '),1)

```

` `  
` `  
And on the side note- I stumbled upon a bug: [Similar actions get mixed up when using abbreviated function name](https://community.mp3tag.de/t/similar-actions-get-mixed-up/56456)
