This is a little error, open the notifier and type in
/setmerit 2 then send. It will be reset.
This is what I perceived happened, if you logged in your telegram account or notification bot on a device that has been previously used to have same notifications but for another account or user, it will continue the counting from where it's stops, so I will advise you check well that you're not connected to another device by mistake or something related for your privacy.
No that is not true, this has happened to be before but I clicked in the Menu and /help that is how I got the idea of setting the main number of merit with just /setmerit and impute your merit number.
