Without your program (source code and .cof file) I cannot check precisely where could be the issue, although LM016L model has been not changed within Proteus version.
However, I would edit both R1 and R2 and try to change the "Model Type" property to DIGITAL.
Also, ensure whether your hardware used PCF8574A as this will respond to a different device address. In this case use the appropriate PCF8574 version in your simulation.
