Asvine Set of 2 Number 8 Fountain Pen Replacement Medium Nibs - Compatible with C2000, V800 and C80- Silver

Looks like you sprung the nib by pressing too hard. It's meant to write under it's own weight, and not be spread like it's a flex nib. It may be fixable, but difficult to say without seeing the nib. If it's not fixable, the nib unit can be replaced https://a.co/d/09wenbuW
