Does the CPZ Form 3/A indicate John S. Koudounis is a 10% owner?

Why is there a Form 3/A amendment for Calamos CPZ instead of a new Form 4?

This Form 3/A is an amendment to the initial ownership report, not a trade filing. It updates or clarifies insider status information, such as officer title and trustee role, and does not reflect new transactions that would typically appear on a Form 4.
