ClearAll["Global`*"]
doesn't clear subscripted variables. It won't clear these variables for example.
Subscript[x, D] = {{0.97, 0.95, 0.93, 0.94, 0.96}}
Subscript[x, B] = {{0.04, 0.05, 0.06, 0.06, 0.04}}
Subscript[x, D]
, etc., are expressions, not variables. Your definitions are stored as down-values of the symbol Subscript
. You need to use
ClearAll[Subscript]
