Default Holley EFI Pro Dash custom ohms HELP

Hi..On my 6.86 pro dash, I used io7 and sensor return for fuel level sensor, which it works but I cannot enter the custom ohms correct .I read empty accurate!

The problem is that I have a 310 empty to 11 ohm full sender (Porsche) . I read it empty(310) , then added a gallon of fuel until it was full at 16 gallons, which coincides with the 16 cells in the Holley, I thought great, just enter the info BUT I can only enter full or low settings, because when you go to enter the second value, it changes the first one to a value I do not want, It is making it's own chart and to enter info on the notepad is SLOW, like when you double tap the cell, the note pad pops up but you have to wait like 5 seconds to enter info, whether using a mouse or touch screen, and sometimes the screen just locks, where I have to cycle the ignition. I did try to click the linearize tabs thinking they were switched "on" but no difference

I was able to add gauges, via terminator inputs, add warnings , everything else but this ..6..0-269 firmware loaded, re-loaded, even un hooked the level sensor and tried to program The dash is reading fuel level, just not accurate. Holley tech..no help, have not found and video on this..Very frustrating!
