Help with filters BGP (p prefix-list > routing filter)

RouterOS General
1

I wish to pass from routers Cisco to routers with RouterOS, but there were problems with filters.

For adjustment of filters in cisco IOS , I use commands:
ip prefix-list Client22 seq 5 permit 22.22.22.0/22 le 24


Prefix-list 22.22.22.0/22 le 24 include:
22.22.22.0/22
22.22.22.0/23
22.22.24.0/23
22.22.22.0/24
22.22.23.0/24
22.22.24.0/24
22.22.25.0/24

I tried to make:
routing filter add chain=test prefix=22.22.22.0 prefix-lenght=22-24 action=accept

but this filter includes prefixes:
22.22.22.0/22
22.22.22.0/23
22.22.22.0/24

How similar options to make on the Microtik?
(version 3.13 and 3.17)

prefix is wrong:

routing filter add chain=test prefix=22.22.22.0 prefix-lenght=22-24 action=accept

use

routing filter add chain=test prefix=22.22.22.0/22 prefix-lenght=22-24 action=accept
