Randomic telegram message on Account Balance Alert with 0.0000SOL

[techno1s]

I activated telegram message and i set threshold in config.toml as "balance_change_threshold = 5.001" (previously i tried 5 without other decimals) but in a random moment I get an alert like this: "Account Balance Alert: Your account balance has dropped below configured threshold, current balance is : 0.0000SOL" but it is not true, because i have almost 10 SOL in balance. Infact in the web dashboard i can see the correct balance. It does not have exact timing: maybe after 1 min, after few secs or after several minutes.

Continues after the screenshot...

Also, immediately after the activation of solana-mission-control and before changing the default value of balance_change_threshold (1000 if i remember) I received messages all the time (correct behaviour with higher threshold), BUT even one with zero.
