As a workaround you can change the NumberNegativePattern to the default one like so: System.Globalization.CultureInfo ci = (System.Globalization.CultureInfo)System.Threading.Thread.CurrentThread.CurrentCulture.Clone(); ci.NumberFormat.NumberNegativePattern = 1; Thread.CurrentThread.CurrentCulture = ci; Thread.CurrentThread.CurrentUICulture = ci;
The fix for this issue will be available with the next LIB (version 2018.3.1105) expected on Monday, November 5.
