We have 2 stores (I just added a new one). In the new store - I initially put in 5 products:
The first one with the correct product name but the other 4 with:
Product 1 Product 2 Product 3 Product 4
as the names of the products.
I later changed those, deleted all the Cache and successfully re-indexed the main store/domain with SSH (Putty):
php bin/magento indexer:reindex
But the products still show the old Product names (Product 1, 2, 3, and 4) INSTEAD of what it actually shows in:
Products --) Catalog --) Product Name
