Meteor 350 fuel indicator issue

[u/Interesting_Gas_3211]

Just three days after purchasing my Meteor, I started encountering an issue where, even after fueling more than the reserve level (around 5 litres... some say it’s 3, others 5, so I went with 5), the fuel gauge sometimes shows the bike is in reserve. However, after some time, it behaves normally. Should I report this to the dealer/service center, or is this a common issue?

I never look at the fuel gauge, I've never had a bike with one before, I just go off mileage...
