Inaccurate date on my nns dashboard

I staked my ICP on the 17th of January 2022, which is more than a year now but in my nns dashboard, it’s displaying 246 days , which incorrect… Pls i want someone from dfinity to respond to this as soon as possible

What is ‘it’? Are you referring to the age? If you top a neuron up or merge it then the new age is a weighted average of the old neuron’s age and the new stake’s age
