Hello there, Kjell! Thanks for getting in touch.
The free version of the plugin is a good reflection of how publishing events works, even with the PRO add-on installed. The PRO version is an extension of the free version that provides additional functionality, such as recurring events. In other words, the PRO version does not change the way events are published and what you are currently seeing in the free version is what you would see when installing PRO as well.
Does this help clarify things a bit and answer your question? Please let me know. 🙂
Cheers!
Geoff
