All courses page do not evaluate the grid/list option

If I change the option “Archive page layout” in course settings to “grid” the all courses page still shows them in list style!

After a couple of minutes code research I found the bug:

The value in database is correct:

select * from wpoptions where option_name='learn_press_archive_courses_layout';
+-----------+------------------------------------+--------------+----------+
| option_id | option_name                        | option_value | autoload |
+-----------+------------------------------------+--------------+----------+
|      5534 | learn_press_archive_courses_layout | grid         | yes      |
+-----------+------------------------------------+--------------+----------+

But the function learn_press_get_courses_layout() tries to get the wrong option layout_course_archive instead of archive_courses_layout (learn_press_ will be prepended later…)

See: wp-content/plugins/learnpress/inc/lp-template-functions.php

...
function learn_press_get_courses_layout() {
        $layout = LP_Request::get_cookie( 'courses-layout' );

        if ( ! $layout ) {
                $layout = LP_Settings::get_option( 'layout_course_archive', 'list' );
        }

        return $layout;
}

And:

wp-content/plugins/learnpress/inc/class-lp-settings.php
...
public static function get_option( string $name = '', $default = false ) {
                return get_option( "learn_press_{$name}", $default );
        }

This is a very simple core feature! Why are there so many really simple bugs after such a long time of development history? I’m really sorry, but I’m a little frustrated about it. So give me chance to understand it. Is the learnpress 4 intended to be for production environment? So when even the installation fails as I wrote yesterday (not all database tables are created after fresh installation) the I can not imagine…

Thank you for giving me a reply.
