Data corrupt? No graphs, only "Invalid Data"

[HeinrichH]

After updating to version 4.3a all my defined graphs are gone, the only screen I get says Invalid Data while with inspect data the data is available.
What am I doing wrong?

Please wait until recomputation has finished.

Do you see errors in "meteohub log"? That might be a reason to worry.

Recomputation is finished, no errors in "meteohub log" see attachement but still no graphs

I noticed in the logfile that sensor "data7" was used 2 times for a different datapoint, I don't know how thats happened because I assigned the heartbeat signal to data8, after correcting this the graphs are back again!
