问个很奇怪的数字筛选问题

C# code

var data2 = cha.Text;
var data3 = he.Text;
 Func<string, bool> Filter2 = x => x.Length == 3 && new int[] { (x[0] - x[1]+10)%10, (x[0] - x[2]+10)%10, (x[1] - x[2]+10)%10 }.Any(y => data2.Contains(y.ToString()));
 Func<string, bool> Filter3 = x => x.Length == 3 && new int[] { (x[0] + x[1]+10)%10, (x[0] + x[2]+10)%10, (x[1] + x[2]+10)%10 }.Any(y => data3.Contains(y.ToString()));
var result1 = Enumerable.Range(0, 1000).Where(x => Filter2(x.ToString().PadLeft(3, '0')));
var result2 = Enumerable.Range(0, 1000).Where(x => Filter3(x.ToString().PadLeft(3, '0')));

算法实现的功能：
000~999一千个三位数序列，Filter2实现：三位数序列的百十差、百个差、十个差 的余数在你的cha文本框中，则输出符合的序列，如cha文本框中输入0，则输出如下
000, 001, 002, 003, 004
005, 006, 007, 008, 009
010, 011, 020, 022, 030
033, 040, 044, 050, 055

完全正确

而Filter3实现百十和、百个和、十个和 的余数在你的he文本框中，则输出符合的序列，同Filter2算法类似，但是却出现了问题，如he文本框中输入6，目前输出如下：
000, 001, 002, 003, 004
005, 006, 007, 008, 009
010, 019, 020, 028, 030
037, 040, 046, 050, 055
060, 064, 070, 073, 080
082, 090, 091, 100, 109
