/loot command returns a wrong message

Steps to reproduce:

1. Summon a witch and execute this command:

   /execute as @p run loot give @s kill @e[type=witch,limit=1]

Observed result:
The message said only 4 items.

Expected result:
The message says 14 items.

The first command block is used to clear all items except the sword, and the second executes loot command.
