Image carousel - missing number insert

iOS: 13.3
Device: iPhone 11 pro

Using an image carousel is missing the number insert (like 2/3)

The first image is shown correctly with 1/3 - but other images (with insert like 2/3 and 3/3) is only presented when the user is scrolling to the next image - then fades away when the next image is reached.

It works nicely on:
iOS: 12.3.1
Device: iPhone 7
