We're happy to help. And to get your question answered even more quickly, it's good to know where we can and cannot provide support.
A theme is merely a visual layer on top of Lightspeed's (or Shopify's) platform/data, and therefore does not have any influence on it's working or data. Everything you do in the backoffice is part of Lightspeed itself. If you have questions or run into issues you can contact Lightspeed support.
