WooCommerce Products & Categories not showing in Trigger Filter

Hello,

I’m having issue setting Trigger Filters in the Flows section of Klaviyo.

I’m attempting to send an email when a specific product is purchased. However, when I try and search for the product it’s not showing up. 

 

As you can see here, Klaviyo can see that there are 6 Items. 

But when I try and add a trigger for Highly Sensitive Thriving Circle - Annual Membership, it doesn’t appear the in Dimension Value.

For some reason only 3 of the products show in the drop-down.

I’d appreciate any advice on what might be causing this. 

​​​​​​​Thanks
