I have the same problem. My current sims family sells nectar bottles and I noticed that all the nectar bottles that was made and stored before the update changed prices after the said update as well. The prices showed when you hover over the bottles were alarmingly lower than their former original price but if you sell it from your sims inventory or the entrepreneur table it still sold for the original prince rather than current price. I tried removing all my mods and starting from a new save with a new sim but the problem is still the same when you make new nectar bottles.
I hope they fix this soon, I'm on my 8-9th gen and my sims only make nectar bottles for a living. T_T
