When Smart Crawl "Title & Meta optimisation" is disabled, our Woocommerce Shop initial page shows the correct title.
When we enable the aforementioned Smart Crawl capability, the plugin sets the page title to the name of the first product we ever added to our store, "Activity Trousers".
Having done a Google search for this, I found someone else seemed to have a very similar issue that the developer said was fixed. https://premium.wpmudev.org/forums/topic/conflict-between-woocommerce-and-smartcrawl-renames-shop-page-title
I've visited the specific page for the "Shop" front end, and tried to manually enter the page title within the Smartcrawl section; however, this appears to be ignored by the plugin.
