Error in json content importer pro3 configuration

Error print in my WP UI.

JSON Content Importer PRO Plugin: <b>Deactivate and then activate the plugin, please.</b><br>This will update the database of the new plugins template-manager1.1)

I deactivate and activate the plugin, but situation don’t corrected.

JSON Content Importer Pro version is 3.8.5, WordPress 6.6.1 and PHP 7.4.33

I try to write new template into my site using ‘Way 2: Add Template’. When I press ‘Save new template’ button. Page says: Failed: Template NOT saved and default template is in editor.

I have multisite pages. I try update site which id is 2.

I check the wp_2_plugin_jci_pro_templates table in database after saving. It is empty. It contain following columns:

mysql> show columns from wp_2_plugin_jci_pro_templates;
+----------------+------+------+-----+---------+----------------+
| Field          | Type | Null | Key | Default | Extra          |
+----------------+------+------+-----+---------+----------------+
| id             | int  | NO   | PRI | NULL    | auto_increment |
| nameoftemplate | text | NO   | MUL | NULL    |                |
| template       | text | NO   |     | NULL    |                |
| urloftemplate  | text | YES  |     | NULL    |                |
| basenode       | text | YES  |     | NULL    |                |

Is this correct?
