Terry:

AFAIK even if you have a symbol named Testarray you don't access its
values with
Testarray[whateverindexhere], you're implicitly declaring a new array

Sam:

you're right, I see something similar with Apply indicator

check with this as an indicator

bc = BarCount;
Plot(bc, "Barcount", colorRed);

see as it plots different levels after you click Apply indicator and
when you slide the graph to see the past quotes, strange behavior...

Looks like a matter for support to me, maybe you should write them, or
I misunderstood how BarCount works, maybe Thomasz or someone more
knowledgeable will come to help...
