There is a small bug within the BizMan Products & Inventory part. The overview of best selling products is also showing SodaCans, but at the moment I’m not selling them as you can see at the right.
Thank you for the report, I have opened a Github issue for the bug:
It’s a low priority issue so it might not get fixed very soon.
I just opend a supermarket and haven’t sold a thing till now, but it shows HotDogs as the best selling product with 56% of sales.
It is a bit different to the above bug, but maybe it is related to it.
Bug has been fixed in the meantime.
