I create a custom module. My admin grid is very strange because it shows randoms columns after the columns I define in my ui-component and no records are found but in database there are records (the add functionality works).

So here is a capture : enter image description here

So here is my ui component code :

</config>

My Database table is named "myvendor_review" and the PK is review_id

In reality ui-component seems to works like layout. So I create an ui-component for a different review system.

I named it by using the prefix "review" (review_listing_data_source, review_listing, ReviewGridDataProvider...) but in practice, it will get the data of the magento module review ui-component and include them in the ui-component. So I changed every review prefix for "customerreview" and now it works well ;)
