Conflicts

Hi, just to flag something. when you change a product in shopify and create new variants, the app still shows your former variants when a customer has to do a manual booking from an email link. this can be confusing as the drop down menu in the manual bookings shows both the previous and current variants, so for example in mine it shows my current service and an old variant option that no longer exists. however it is not possible to delete the old variants from the main product menu. so for one product i have four variants, and only those four show up which is good, but the menu says 13 variants exist, and then makes them available in manual bookings. could you possibly fix this? I seem tonget a lot of conflict bookings at the moment, even when the client has chosen their date and time for their appointment when booking, which they get fristrated by. i think this may be a conflict with them using apple pay to check out, or whatever they are doing wrong. but i have quite a few conflicts right now and not sure why. thanks! pete
