Repeating group - cell index number calculates incorrectly when RG is dynamically extended

Overview

  1. I’ve got a repeating group with max rows 2 + a button “Show more” which will increase this value on click
  2. Repeating group items are displaying cell index value

Issue: when dynamically extending Row count on Repeating group, the index value will calculate incorrectly starting the item# which was made visible by clicking ‘Show more’
Note that issue doesn’t exist if you are showing all rows from the beginning, which is a workaround.

Update: I realise it’s actually a bug, so I went ahead and reported it to Bubble straight away.
Posted this here in case someone else will notice this behaviour and would look for the information.
