I did an import of related products (re_skus) using Magmi and Magento 2.2.3 recently, and on the front-end the data is correct. However on the back-end, only 2 related products are shown as being attached to the main product. I checked all main products from my CSV and it's the same for all -- just 2 related products in the back-end (but there are really many more that are related). No errors or anything in Magmi console.
I tried reindexing, clearing caches, etc. but still no success. Any ideas?
Thanks in advance!
