The Events Calendar Pro + Filter Bar Plugin: Filter Bar shortcodes not working, all plugins up2date

As written in the title, I tried to close the vulnerabilities of an older The Events Calendar Pro plugin today by purchasing the latest version of it. I followed by updating the free version and filter bar needed to use the codes with it, which worked fairly well until today. Sadly, even though all shortcodes are fine and the main calendar is working, in subpages where the calendar was shown via shortcode the filter bar is not showing the calendar anymore. Since the only change from my side was updating the plugins to the last version, I fear it is dependant on the update. Thanks for looking into it, if someone has an idea how to solve this issue, many thanks in advance!

Thanks
