I have started working with magento earlier this year, I am running magento CE 2.2.2
I have noticed that when I go back to edit a product from the catalog I have noticed that the categories are not listed.
I have checked the frontend and item visible in the category, the problem is in the backend, you can see the attachment image below.
Does anyone encounter the problem or know a solution that can be applied?
here you can see the categories I chose during product setup: image url
but it is showing like this when I go to edit, which makes it impossible to edit categories: image url
