THIS IS NOT A FIX
I was encountering this issue too, but after more adjustments I have gotten the phone to "semi-work" by limiting "L5_1" to just two variables. (Removing L8_1 through L14_1, leaving just L6_1 and L7_1)
So while this probably breaks other things, it at least is helpful in moving forward IF you are attempting to reverse-engineer this.
