Additional clarity:
Before converting a column from list to search (with the list in the filter that the UI automatically does) ALL results work where it shows all in the list, but if you convert to search where you only want to see certain things for that list is when things have an odd "break date".
Trying this with different lists creates different break dates (where no new content is show after that date).
Again: Multiple browsers, multple devices, multiple ISPs, cache, cookies, etc all cleared. Issue is one of two things: Account issue where UI is broken or UI is broken more broadly.
