Every time customer tries to add item to cart, the wrong variant is added.

Hi there, I am currently trying to figure out what is going on with one of our online stores.

Every time a customer adds an item to the cart, the wrong variant (size) is being added. 

This is on a wholesale site we have set up and we have never encountered an issue with our main store so I can't really seem to troubleshoot this.

Hello @DevinFortyNine ,

 Most of the time it happens because of the JS conflict. 
Can you share your store URL so I can check and confirm? 

Thanks

Hello @cleanherbalsAU ,

You can DM/share the store URL, so  I can check and let you know the issue.

Thanks

Issue is a conflict. 
On change of the variant you can see this error in the browser console
Uncaught TypeError: _.map is not a function

To fix it:
Revert the changes you did recently.
or

Uninstall the apps you installed recently.
or
Call a developer to check the JS and fix it.

I'm a developer too but you can pick anyone you want. Developer contact found in the signature.
