Page Event name not getting displayed in Sitecore 9.3

Question

We are migrating from sitecore 8.2 to sitecore 9.3 and having some custom page events to register few actions from our users. While debugging the code we could see the event name, event id everything getting added perfectly but in sitecore experience profile under events we are not able to see event type and name of event formed properly. Please see attached screenshot from sitecore 8.2 and sitecore 9.3 for reference.

Name displayed in Sitecore 8.2 -

Name not getting displayed in Sitecore 9.3 -

Custom code -

 [CLSCompliant(false)]
    public class TrackEvent : MarketingDefinitionBasedEventProcessor<EventInstance, IPageEventDefinition>
    {
        protected override bool IsValidEvent(EventInstance eventInstance)
        {
            return !string.IsNullOrWhiteSpace(eventInstance.EventId);
        }

        protected override IPageEventDefinition ResolveDefinition(EventInstance eventInstance, TrackEventPipelineArgs args)
        {
            return Sitecore.Analytics.Tracker.MarketingDefinitions.PageEvents.FirstOrDefault(
                e => e.Id == new Guid(eventInstance.EventId));
        }

        protected override void DoTrack(IPageContext pageContext, IPageEventDefinition eventDefinition, EventInstance eventInstance, ITracker tracker)
        {
            if (tracker.IsActive && tracker.Session?.Contact != null)
            {
                Sitecore.Analytics.Tracker.Current.CurrentPage.RegisterPageEvent(eventDefinition);
            }
        }
    }

Answer 1

This issue is resolved now and we are able to see the page event names in sitecore experience profile. In our publishing targets, we have 2 databases - staging and web. So we published the events to staging database as well this time. Earlier we were publishing it only to web. After publishing to staging database, the names started to show.
