If it was working without the switches, then you need to change the HAL and INI files to use the switches after you add them.
In the Axis preview window you will see a little arrow appear next to the DRO position display for each axis when the switches operate, and clear when the switches clear. The first test to do is to manually operate the switches and see if you can see these change state.
If they don't, then the likely problem is that the switch inputs are not connected to the home/limit pins in HAL.
