Products showing in collection it is not assigned to

[pije]

I have a product (see screenshot) that is showing in a collection that it is not assigned to... On the screenshot attached it shows the collections that it is assigned to, and yet it is displayed in this collection: 

https://17f4d8-3.myshopify.com/collections/shirts-and-shirtdresses (password is lausey)

I have several products with this behaviour, showing up frontend in collections they are not assigned to. When I check the collection in admin, the product is not listed in the collection.

Does anyone have a suggestion how to fix this?

Hi @pije 
It may be the case that you are using some filters app on the collection pages and products are not correctly synced with the app, you can contact app support they will sync the products and then it will work just fine
