What a licence covers

Removing is never paid for

“Remove pre-flight tabs” deletes the generated tabs. It is part of the free tier and always will be. Your source tab is never touched either way — there is nothing to undo there.

Refunds

Ask and you get one, within 30 days, no reason needed. Refund policy.
