I have a similar, although different, problem, but I have it with the Send MSC actor. The problem is that the "Cue number" input is expecting a number, so in fact cue numbers 123.4 and 123.40 become the same cue.
I'm using this actor to control a Lanbox LCX. Of course, an easy work-around is to not record any cues that end in zero, but I'm wondering if there's another solution. BTW, I already reported this bug.
