Ships in the night - Ahoy!
I've been following the discussion, and of course, I had to check with my sample of WFB. When I open it, and add the date picker without setting any from date (nor to date) I get today's date, May 26th 2023. Not 2026 or anything fancy like that, just today's. I think the default in the app is set to show the actual date of the day it's opened.
I tried doing like in Frank's video, setting it a couple of years in the future, and I got the same result as he did, also when it went back to today. It may be that there is something lingering in the app, keeping the date settings in the options for the date picker a tad too long. You could perhaps try to set it to some fake date and year as the last thing before you close down for tonight, and then, as the first thing tomorrow morning you open WFB again, pop in a date picker without any settings, and see if it still remembers what you did the evening before. Or maybe even just a reboot of your machine lets WFB forget past settings.
