Formula still showing previous dates

[Neilemmo]

I am using this formula in a slice to show expiry dates within the next 90 days:

([Expiry Date] <= (TODAY()+90)), ISNOTBLANK([Expiry Date])

At the minute the formula is working for the 90 days and I can’t see records that expire after 90 days. HOWEVER, I am still seeing records that have already expired (see below)
