I have a script that decodes the genre to assign a grouping value.  This script has been in place over several Picard releases and has been working like a charm.

I am now seeing odd behaviour in that, instead of the grouping value being set as expected, it always contains the genre value!

The script (snippet) is as follows:

$setmulti(grouping,%genre%)

$replacemulti(%grouping%,16-bit,Electronic)

$replacemulti(%grouping%,2 Tone,Reggae / Ska / Dancehall; Rock)

$replacemulti(%grouping%,2-Step,Dance; Electronic)

$replacemulti(%grouping%,3-Step,Dance; Electronic)

 ...

$setmulti(grouping,$unique($sortmulti(%grouping%)))

What I am seeing is, using the above as an example, if the orignal genre is 2-step I'm seeing the grouping as 2-step when it should actually be set to Dance; Electronic

I'm not sure if it is the $replacemulti or the initial $setmulti that is the problem
