Hi，I got some weird residuals of the static in Equation number 7、10、11.Could you help me find out what’s wrong?

Residuals of the static equations:

Equation number 1 : 0 : 1

Equation number 2 : 0 : 2

Equation number 3 : 0 : 3

Equation number 4 : 0 : q

Equation number 5 : 0 : 5

Equation number 6 : 0 : ir

Equation number 7 : -1 : 7

Equation number 8 : 0 : x_1

Equation number 9 : 0 : x_2

Equation number 10 : -Inf : 10

Equation number 11 : -Inf : d

Equation number 12 : 0 : mc

Equation number 13 : 0 : y

Equation number 14 : 0 : 14

Equation number 15 : 0 : rk

Equation number 16 : 0 : 16

Equation number 17 : 0 : 17

Equation number 18 : 0 : 18

Equation number 19 : 0 : K
