Products into variants if imported from AppScenic.

Hi, we currently use AppScenic to import products to our shopify store. We are having an issue with integrating existing product variants into one listing. Example would be a bag available in three colours, currently we have no option to create these a variants in one product card. We have tried the add variant and duplicate variant, however these does not seem to work for AppScenic. Anyone else have this issue and is there a way to resolve it.
