Slice that only shows rows with the current month

[emilioudi]

Hello!
I was trying to create a slice to only show me rows from the current month.
for the row filter condition i put:
AND( MONTH([Date]) = MONTH(TODAY()), YEAR([Date]) = YEAR(TODAY()))

when i save the expression assistant it shows me the right results in the app preview but when i save and reload the app it doesnt work anymore.

is the formula correct? Thank you for the help!
