List filter does not work without updating the webpage

Hello!

In my appointments list i have a formula column with this formula:

date(start('date')) = today(), which i filter by Yes value to see only today's appointments.

 It worked well every day until maybe 2 months. 

Now, when i check the list in the morning i see yesterdays records.
When i press the update button (that circle arrow) above the row numbers today's appts show up, but yesterday's ones do not disappear.
To make them disappear i need to refresh the whole webpage in the browser.

Is it correct behavior or the update circle icon should do it without refreshing the webpage?

Thanks a lot,

Agassi
