@samah,
The course creation will be managed by from here:

Please do check the tutorials how to setup wplms 4+ properly
Second thing is once vibebp and wplms plugin is installed and activated make sure the vibe course module, vibe customtypes, vibe shortcodes, wplms frontend, wplms dashoard. These plugins should be deactivated
You need not purchase the vibebp plugin separately. Once you upgrade the theme version. You will automatically get the plugins in appearance -> install plugins section
