How do I split up one variant option into two variants on an imported product?

[BonoboEarl]

I am currently building an Apple Watch strap shop. I have the following problem: 

One of my straps has the following three options a customer can  choose from: 

- Color (Red ; Blue ; Green ; etc)

- Apple watch size (38/40mm ; 42/45mm)

- Strap size (S ; M ; L)

After I imported the product through Oberlo (its an aliexpress product), The options Apple watch size and Strap size are for some reason bundled together into one variant. Meaning: 

Variant 1: color 

Variant 2: Apple watch size (38/40mm ; 42/45mm) with the different strap sizes S, M, L.

Variant 3 isnt available, since its put together into the variant two. 

Ive included a picture that underlines my problem and shows what I mean. 

I am  helpful for any advice on  how to fix this, while still being able to keep  a working connection between the shopify shop and oberlo/aliexpress supplier. 

Thanks alot!
