Does not find items matching the item filter specified in the aggregation function

Hello!
The host has items with the "Sessions [1540,*]" keys (screen1).
An item with the "calculated" type was created, the "last_foreach" function was used in the formula, to which the item filter was passed (screen2).
When testing, I get the error "Cannot evaluate function: no items matching query at "last_foreach(//Sessions[1540,*]))". When creating an element, it becomes unsupported with the same error (screen3).
When queried directly to the database by the item filter specified in the formula, these items are found (screen4).
Tell me, please, what could be the reason for the error?
Thanks. Good day!
