Buffer Pool Instances Doesn't Work

I have a new standalone Windows 10 installation. I've changed the buffer pool instances through

SET PERSIST innodb_buffer_pool_size = 8589934592; (8 Gb)
SET PERSIST_ONLY innodb_buffer_pool_instances = 16;

Default innodb_buffer_pool_chunk_size = 134217728 (128M)

When I restart, actual and persist values for innodb_buffer_pool_size are correct, while innodb_buffer_pool_instances persist value shows as 16 but actual value reported is 1.

As far as I can tell, the above values fit the rules for these settings of pool size divisable by chunk * instances. These are also the values in the MySQL 8 manual used as an example. I can't understand why it won't set the proper value for instances. There are no errors in the error log.
