they are centered with the name you have given the sizes underneath
see here what this typically looks like

but as you have chosen to make the “sizes” name something like “box of strawberries 500 grams” you’ll have to set the css to be right aligned if you want it that way

PS: something in your site also inexplicably adds things like
<font style="vertical-align: inherit;"><font style="vertical-align: inherit;" class="">3.00</font></font>
around the prices…
just mentioning it , it’s certainly not wppizza doing it
