I set up the AXI slave with 32 registers. As my design got further along I discovered I needed 40 registers. So in an attempt to add to the address width I opened the wizard in IP customization Parameters tab. I double clicked on the AXI address. I could see it was set to 7 as the maximum so I closed it. Now I get an error [IP_Flow 19-345] User Parameter 'C_S00_AXI_ADDR_WIDTH': Default value 7 is greater than the validation maximum 0
The local address width is still 4 for 32 registers and I cannot get rid of the error.
