As I said before, it is very likely one of the default values is not set, though I haven't checked this. This will have the effect of setting that value (what value I don't know) to 0, which is almost certainly invalid.
The solution is the same in all cases. Run the tuning program. Unless it is also buggy, you will get a valid set of values and won't have to rely on possibly erroneous or missing fallback values. I think you are confusing the value that you are setting from 11 to 0, both of which are valid, with *other* missing tuning values, which then default to 0. There may be a constraint that the *other* value needs to be greater than the value that was set to a default of 11. The tuning program knows this. Apparently the fallback values do not. Bill.
