The Quick Play buttons almost never display the correct information. My current game, which I’ve been into twice already today, says “17 days since last launch”. Earlier today, it said “16 days …”.

I couldn't reproduce.
However it will be better if you report this to the Minecraft Launcher channel (https://report.bugs.mojang.com/servicedesk/customer/portal/7)
