How do I fix selection issues in my online store?

Can someone please help me. One of my stores requires you to select a shape, size and colour but for whatever reason it only allows me to press one button from all of the options. Can someone tell me how to fix this. I have provided a screenshot from my store and another store to show an example.

@Brandonf140 - these are variant options created using radio buttons and only one radio button can be selected from the entire group of them

How can I fix this without using drop-down menus?

@Brandonf140 - drop down or radio buttons, both will allow only a single option to be selected
