Third Variant on all Products Disappearing

[SeanConnors]

So I'm having an issue with the site: https://aquafliesdealer.com/

Out of nowhere, all products with more than two variants only show the first two. The weird thing is that for a split second, the third one pops up for a millisecond before disappearing. For instance, the page at the link: (https://aquafliesdealer.com/products/conehead) should have three variants but only two appear. 

Any ideas as to why this is happening and how to solve it? Thanks!
