While creating variants -

It works fine if we clone/add variant from the overlay options

But, if we add/clone variants from the buttons at bottom, it skips one variant (Which leads to white screen & unable to edit. For example I already had Variant A to D. And I tried to clone one of them, it created Variant F instead of E. But the list of variants shows A - E only. And variant E shows blank screen.

I'm on Altis v19, PHP 8.2 & WordPress 6.5
