When I looked at it you had it set to OPK for detecting O. I know in your OP you said you turned that off but make sure that when you do that you have it set to advanced. Double and triple check your settings. .
Oops, sorry I didn't clarify, when putting in dummy temperatures did nothing, I set it back to OPK.
ha! You can't get CH with four missing temps at O time. lol.
As I said above, fo sho. But even putting in dummy temperatures did nothing, this my confusion. FF is probably just on to me. ;)
