Basically what i am trying to implement: 

Segmenting customers based on whether they have purchased the any product in category X and presenting separate offers to buyers and non-buyers. 

In short: I am trying to build Cross-Sell Flow. 

But there is a problem: I cannot see all my smart collections in the flow filters

However, i have many collections. And Klaviyo actually can see all of them too.
 

 
The second problem (and probably linked to the first problem) is:

When i place an order online to see how my products are recorded on Klaviyo, i have this result:

 

See that there is NO COLLECTIONS.

However, on shopify actually Smart Collections are assigned for that specific product.

Note: Before purchasing the product, I have waited for 15 minutes and syniced all the products and collections on Klaviyo.

I think that’s why placed order metric cannot be filtered by all of the categories i have.

Any solution for this problem? Thanks in advance.
