expire date wrong?

[Techtobi83]

Hi all,
forst of all i want to thank you for sharing this great solution to catch Libre sensor data for smarthome usage.
I use your paket for about 2 weeks now, everything looking good, but i see one problem:
Today i changed my sensor. Also the expiry date changed, but while my libre app says "next date of expire: 29.12.2024", here LibreView says "next date of expire: 25.12.2024". So not 14/15 days but only 10 days.
What am i doing wrong?
