Only some of the rows are cloned and strange entry “wp_2_user_roles”

I have one primary page in multisite wordpress. I am trying to clone it. Unfortunately, from each table only some of the rows are cloned. There are no errors in the server logs. For example, in the table “wp_options” I have 281 rows. The plugin clones only 13 of them. In the plugin logs I see such strange entries:

?	GENERATING create table query for wp_2_options:CREATE TABLE wp_2_options ( option_id bigint(20) unsigned NOT NULL AUTO_INCREMENT, option_name varchar(191) NOT NULL DEFAULT '', option_value longtext NOT NULL, autoload varchar(20) NOT NULL DEFAULT 'yes', PRIMARY KEY (option_id), UNIQUE KEY option_name (option_name), KEY autoload (autoload) ) ENGINE=InnoDB AUTO_INCREMENT=99678 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_520_ci

... etc.

I have used your plugin with other sites and this is the first time I have encountered something like this. Why is there this strange condition in these sql queries?

WHERE option_id > 99150
WHERE option_id > 99677
WHERE option_id > 99677
WHERE option_id > 99677
... and so to the end

I also don’t understand why the plugin adds such a row in the “wp_options” table:

option_id | option_name | option_value
99677 | wp_2_user_roles | a:12:{s:13:"administrator"...

It seems that the plugin later clone only those rows from this table if they have id>99677.
