Repeater not working when placed inside Flex::make()

I’m facing an issue with the Repeater component and wanted to confirm if this is expected behavior or a bug. I have a Repeater field (for probation extension periods) inside a Flex::make() layout, basically to align them horizontally for a clean UI. Issue is: The first repeater item cannot be deleted if it’s empty. When I click the delete button, only field values clear — the row remains. Second repeater item adds more than one field and sometimes 4 to 5 fields. Is it a known limitation that Repeater shouldn’t be placed inside Flex::make()?
