Bug report 4.5.1 fails to Load bars to variables 16 of 28 pairs

Hello Team,

I have the below code, to load 28 FOREX pairs to variables as private Bars. It works with no problem at 4.4.19 and all previous versions. But 4.5.1 report error as below screen shot.

using cAlgo.API;

        [Parameter("GROUP B",       DefaultValue = "True",          Group = "Ver. 2.08"     )] public bool   GroupB     { get; set; }
