Modify via CSV only validates 10 records?

Whenever I used to modify records via CSV or upload ones, it would always validate every record when I press validate. So if there’s 5,000 rows it would go up and up until it said 5,000 validated. Now it only ever says validating 1 of 10 and then hits 10 and says complete. Does that mean it no longer checks them all?

Also, is there actual support with paid subscriptions? I emailed Bubble support over 3 weeks ago with a bug in my application I can’t fix and no one has ever responded. Disappointing when paying $400+ a month for something.
