Can't plot 1st AddDataSeries("DX 12-15"...

[ProfitPilgrim]

Strange. In my custom NT8 indicator I added 3 data series. The first (as well as the others) were coded like this:
AddDataSeries("DX 12-15", Data.BarsPeriodType.Minute, 1, Data.MarketDataType.Last);

When I reference them in the code for plotting, the second and third added series plot fine but the first (DX) doesn't plot at all. I reference it like this:
MTNhighs[0] = (Highs[1][0]);
When I reference the 2nd and 3rd added series as Highs[2][0] and Highs [3][0] respectively they plot fine. I tried adding the symbol as DXE 12-15 instead of DX 12-15 at ampclearing's suggestion from a non-programmer in chat support there since the data is from CQG and it originates as DXE at CQG according to him, but it didn't work. DX 12-15 plots on my chart fine so I assume the code for the added symbol should be "DX 12-15"

If I place another symbol in the 1st added symbol position in my code that symbol plots fine still using "Highs[1][0]". Not so with DX, which doesn't plot regardless of position

I even tried connection to another datafeed (Rithmic) thinking maybe it was a symbol issue but no bananas.

Any clues why I can chart the symbol DX fine but not refer to it by the same name in an indicator and have it plot
