I am trying to use our own flasher for a Micron 32MB (MT25QL256ABA) on a spi bus. With J-Flash V7.88
But I get some strange info and behavior when selecting the flash.
Create the project

But by default the "Sector selection" only selects the first 65535, then select the rest

Then also the "Sector selection summary" is also wrong
