How to lose money when getting things right

I feel truly regarded. Bought AVGO call spread ($225 - $230) when AVGO was under $225 (approximately 365DTE). Now AVGO is $229, yet somehow the $225 strike call option increased in value much more slowly than the $230 strike call option.

I can't even pretend to know options anymore.

EDIT: Thank you so much everyone. I learned some shit, so can start pretending to know options again!
