AWS RDS MariaDB slow logs empty rows

I enabled the slow query logging on my AWS mariadb RDS as described here. And set up the publishing to Cloudwatch logs.

Parameter group family:

mariadb10.11

My parameters:

log_output = FILE
log_slow_query_time = 0.2
log_slow_query  = 1

This works, as my slow querys are logged to Cloudwatch

use db_name;
SET timestamp=1724932120;
SELECT SLEEP(0.3)
LIMIT 0, 200;

But in addition to that there are also many log rows, that usually come after that.

This makes it harder to find the actual slow query. How can this be disabled?

I have tried:

log_slow_min_examined_row_limit = 1

But with this parameter still these rows appear
