SwiftUI list not showing all items - ios

Question

I am trying to show a list of side-scrolling list in iOS. Some of the lists show but others don't, even though they all have data. I put a debug point and see that the ForEach with EventItemView is called for every section. I am unsure of what I am doing wrong.
EventScreen
struct EventScreen: View {
#State
var currentPage: Int = 0
var viewControllers =
IncentiveSource().getFeaturedIncentives().map({ incentive in
UIHostingController(rootView: EventFeatureView(event: incentive.toEvent()))
})
var response: [EventSection] = IncentiveSource().getIncentives().sections.toEventSections()
var body: some View {
NavigationView {
List {
EventViewController(controllers: self.viewControllers, currentPage: self.$currentPage)
.listRowInsets(EdgeInsets())
.frame(height: 600)
ForEach(self.response) { section in
EventSectionView(eventSection: section)
}
}
.navigationBarTitle(Text("Events").foregroundColor(Color.black), displayMode: .inline)
}
}
}
EventSectionView
struct EventSectionView: View {
var eventSection: EventSection
var body: some View {
VStack(alignment: .leading) {
SectionTextView(text: eventSection.category.typeName())
.frame(alignment: .leading)
ScrollView(.horizontal, showsIndicators: true) {
HStack(alignment: .top, spacing: 0) {
ForEach(self.eventSection.events) { event in
EventItemView(event: event)
}
}
}
}
}
}
struct SectionTextView: View {
var text: String
var body: some View {
return Text(text)
.bold()
.font(.system(size: 18, weight: .heavy))
.foregroundColor(Color(ColorTheme.brandBlue.value))
.padding(.bottom, 4)
}
}
EventItemView
struct EventItemView: View {
var event: Event
var body: some View {
VStack {
Color.red
.frame(width: 100, height: 100, alignment: .center)
.cornerRadius(5)
Text(event.title)
.bold()
.frame(width: 100, alignment: .leading)
.foregroundColor(.white)
.font(.system(size: 10))
Text(event.date)
.frame(width: 100, alignment: .leading)
.foregroundColor(.white)
.font(.system(size: 10))
}
.padding(.trailing, 8)
}
}

It needs to make each horizontal scroller in EventSectionView unique like below
struct EventSectionView: View {
var eventSection: EventSection
var body: some View {
VStack(alignment: .leading) {
SectionTextView(text: eventSection.category.typeName())
.frame(alignment: .leading)
ScrollView(.horizontal, showsIndicators: true) {
HStack(alignment: .top, spacing: 0) {
ForEach(self.eventSection.events) { event in
EventItemView(event: event)
}
}
}.id(UUID().uuidString() // << unique
}
}
}
