No data older than 7 days?

I was looking at my data on beestat (thermostat detail graph) and tried to look at data from about 3 weeks ago and it keeps telling me there is no data. I manually entered the dates, I tried starting from March 5 and March 15th. Data from the last 7 days is shown normally. Am I doing something wrong?

If it’s any consolation I tried it and got the same result. I tried 3/1/2021 through 3/30/2021. It accepted the range but showed no data.

Found a bug. As a workaround set your range then refresh beestat and it will load. Thanks for the report!
