Raspberry PI temperatures, voltages and states

Since some time the Raspberry PI temperatures, voltages and states aren’t visible in the GUI.
I’ve tried to remove the host and added it again, but it doesn’t show up anymore.
Also the Raspberry PI application is missing.

Validation (schema isn’t valid due to switch to stable release):

====================================

Component Version

[WARN] Your schema (268) is newer than than expected (262). If you just switch to the stable release from the daily release, your database is in between releases and this will be resolved with the next release.

Does anyone have the same problem and knows the solution?
