Repeating group always render with extra cells

I need help to solve this issue
repeating group always renders with extra cells before it renders the actual number of cells
this happens for only a few seconds

What’s the datasource of the RG?

I checked those extra cells with the inspect tool and they are all empty with no id

Happens alot in my experience but it’s usually not a deal-breaker in my opinion. What u can do is to have a plain background colored group to block the RG while its loading.

This is different from hiding the RG cause a hidden RG won’t load so you need the RG to be in a visible state. The “blocker” group is just there to hide any jankiness.
