I'm not sure what I should be looking at in those screen shots.

Here is an example, this is from the daily status email I have it sending me.

Alkalinity : $$SENV[k]$$
$$REPS[32][0]$$$$SEND[x]$$ : $$SENV[x]$$
$$REPE$$

This sends:

Notice how any label that is 16 characters gets concatenated with the label following it. Like with "Sump cooling fan", "TurfScrubberLigh", "Skimmer neck cln", ...

And it sure would be nice if you got rid of the 16 character limit! It forces people to abbreviate the names of things. I suspect your code is "C" code, with fixed array lengths... This would be a pretty easy thing to fix.
