ProxySQL exporter returns odd values

I’ve tried to setup dashboard to get an email once any of slave servers is out on proxysql pool
however it appears proxysql_connection_pool_status returns values other than 2,3,4

Kindly see prometheus/graph attached,
the metric returns 1 for ONLINE, but once server got SHUNNED , on reached max_replication_lag treshold, the metric returns some 3-digit values, that actually looks like some random values .

In addition,

As I see “Proxysql overview” dashboard works fine and shows status correctly, However graph shows weird values, I’ve set an alert in Grafana based on graph and see that random values on emails and alert history as well
