Why there is still an approved comment after deleting all?

@Nikolay Yes well, I checked the database, there were no post, pages or products at the time, but then someone left a comment while I was testing with the “under construction” disabled, once I answered this comment everything turned out alright, the invisible comment was gone and now there are only the two comments, one by a visitor and one bt me, my friend said she had the same experience, I suspect its something with woocommerce, possibly the action button to set up the settings that keeps on reminding you, either way, its all fine and clean now, thank you so much for your assistance.
