It sounds like your issue might be related to your WordPress settings rather than WooCommerce. You should post anything related to WordPress in the Fixing WordPress Forum.
However, you can change the number of blogs displayed by following these steps:
Go to your WordPress Dashboard.
Click on “Settings”.
Click on “Reading”.
Look for “Blog pages show at most”.
Change the number to the desired amount (in your case, at least 7).
Click “Save Changes” at the bottom of the page.
Please note that this will change the number of blogs displayed site-wide. If you want to change the number of blogs displayed in a specific place, you might need to adjust the settings of that specific widget or plugin.
I hope this helps! If you have any other questions, feel free to ask.
