This issue is related with ListView GroupHeaderTemplate produces blank headers on iOS #19186. When performing expand and collapse action for the groups of ListView and also scrolling the items of ListView, the group headers are missing on iOS and MacCatalyst. You can follow up there.

As an alternative workaround, we suggest you can use CollectionView rather than ListView. As the previous one won't have issues displaying the headers in this scrnario.
