Problem in AXI4lite to APB address mapping

 Sir/Madam, I have been receiving a warning as APB slave is unmapped even though it is mapped in address editor. It is showing address disjoint. Moreover in APB to AXI4  converter it showing different address and is not allowing me to change it. I am not getting what vivado is trying to say with that warning. If I go ahead neglecting that warning then I am getting problem at Linux level as my host processor is not able to recognise my device. I attached a part of my block design, Address mapping and AX4lite to APB ridge properties. Sandlogic IP is my custom IP and I am trying to connect it to a host processor. Thanks in advance.
