Strategy-Parameter-Label-with-Commas-Resolved

I am using below selection (1 for A, 2 for B and 0 for A/B) as follows in c#:

CODE:
AddParameter("1 A, 2 B, 0 A/B", ParameterType.Int32, 2, 0, 2, 1)

when you press on strategy settings the "Save parameter's as strategy's default" the strategy code is changed causing an error as follows:







ie. the selection disappears from strategy settings and the parameter text in the code is changed causing an error

this must be a very particular combination causing this error - as all other parameters in strategies seem to work well. am I doing here something wrong? thanks WL team!!
