Tile size can't be changed

So I changed background to blurred and found tile size had reset to normal. After that I have been unable to change them back to small. I tried restarting and changing the background to not blurred again. Help?

Hi there
Did you try option
“Use small tiles” in tiles settings?

Yes, that is the one that is not retained when I exit settings.

Restart Ratio manually. Then change the settings. It worked for me

Thanks! That worked, at least for now.
