Why WPLMS WooCommerce Plugin is not active/installed?

Hi, Your Theme is quite nice but also really complicated to use. At the end, we bought WPLMS because it says that WooCommerce is integrated. (See picture below) Now we found time to install the theme and so we wanted to link a course to a simple and "free" product from WooCommerce, as described in the tutorial (https://www.youtube.com/watch?v=wjE5uGKTuXM). And also wanted to use the described ability to create account with simple product here described: https://www.youtube.com/watch?v=CBQmpOuPBAE   Unfortunately the shown setting «select box» WPLMS: in Products Data (https://youtu.be/wjE5uGKTuXM?t=16) was not shown. Also the settings for Courses were missing. So we have searched for the reason/bug and found this information about: https://wplms.io/support/forums/topic/wplms-woocommerce-addon-functioning/ With the link to :http://vibethemes.com/downloads/wplms-woocommerce/ We can not understand, why on your website (see above) you advertise with «Integrates WooCommerce» when we would have to pay again for, before we could use WPLMS with WooCommerce. So we think, there was a miss-installation or some install-bug because the plugin WPLMS WooCommerce should be also installed by default. Otherwise your promise «Integrates WooCommerce» would be totally wrong. Please could you get us an information, what we have to do, so the WPLMS WooCommerce Plugin will work without paying for am advertised/promised and thus already payed feature? Thank you in advanced for a working solution. Martin
