take a look at the chart... may be a chart glitch?... @beefyfinance

Answer2:If the chart glitch persists even after you have changed your RPC, then it could be an indication of a larger issue within the network. It is possible that the network is experiencing high levels of congestion or that there is a bug in the system. In either case, it is best to contact the Matic team directly to get further assistance. They may be able to provide more insight into the issue and suggest a solution.

Try changing your RPC, pick one from this site: https://cointool.app/rpcServer/matic You can pick the lowest latency one
