Failed to uncheck the option of ‘change slides by clicking on background

In LibreOffice, I am trying to create a PPT. I tried to uncheck the option of ‘change slides by clicking on background’ in slide show setting. then I saved the PPT and close the PPT file, after that I tried to open the PPT file again, then I found the check is back.

that means the setting cannot be saved

my version of LibreOffice is 25.2.2.2.

same with .odp ?
