Selected options not showing on emails or print outs

Hi Maartin, thank you for the plugin. I use it for my restaurant and mainly for two products, a custom pizza and a dipping sauce. I created the custom pizza a long time ago and never have had issues with your plugin on that product, it works just fine. Later, I created another product called Sides and using your plugin customers are able to choose a flavour of dipping sauces. Unfortunately I get random results for the Side options. Last week they worked and this week they do not. What I mean by not working is that when a customer makes a selection using the plugin options, their selection is not visible on the email we receive thats generated by WC. It only shows the word Sides and the price but not the selected flavour to go along with it. I have had this issue in the past and deleting the product and re-creating it works but eventually stops. Im not sure why, I do not touch it once the product is created.
