**Export code example 1** :

```
%_total_size% => $replace(z0z %_total_size% z0z,0,X)

```

**Result** :

```
104,27 MB => z0z 104

```

**Expected** :

```
104,27 MB => zXz 1X4,27 MB zXz

```

**Problem** :  
No replacement at all and things after %\_total\_size% are not even included.

Export code example 2:

```
%_total_size% => $replace(z0z $trim(%_total_size%) z0z,0,X)

```

**Result** :

```
104,27 MB => zXz 1X4 zXz

```

**Expected** :

```
104,27 MB => zXz 1X4,27 MB zXz

```

**Problem** :  
%\_total\_size% does not have any unit nor decimal part.

Same behavior can be observed with $regex(), and I'm guessing other (string) functions. Is this bug by design?
