Issue with the performance data after upgrade from 1.6.0p25 to 2.0.0p22

**CMK version:2.0.0p22.cee
**OS version:Ubuntu 20.04

I looked into the Performance graphs of some filsystem checks and some of the metrics only had data for past 30 days.
But when I look at Check_MK service check then historic data is availabile.
