Missing Z end stop on lowrider 4

Good Morning Ladies and Gents.

I am helping a friend build his lowrider 4 and last night we were setting up the end stops but when i run M119 I only see and end stop for Z max and Z probe i done see a second end stop for Z.

I am running an SKR 1.4

Dual end stops

Firmware version. V1CNC_Skr1p3_DualLR_2209-2.1.1.zip

I changed the board in the firmware to SKR to 1.4 and complied the firmware.

I’m pulling my hair out not sure how to fix it.

Graham.
