Incompatible with many events plugins

Unfortunately many event plugins try to make usage easy by injecting their event data to WordPress pages and posts. Unfortunately they don’t discriminate between regular posts and custom post widget content blocks. Usually you can circumvent these kind of issues by modifying your theme’s template code to include the event data instead of letting the event plugin do this automatically. If this is not possible you could also try checking the ‘do not apply filters’ checkbox on the content block widgets.

Please let me know if this helps.

That is good to hear!
