Hi!
After a fresh installation of icingaweb2 there is shown on every site of icingaweb2 unwanted performance data. I don’t know how to deactivate them. On some sites they use a lot of space so that other wanted infos are no more viewable.
The Icingaweb2 benchmark mode is enabled for your account.
To diable it got to https://icingaserver/icingaweb2/profile and uncheck the option “Use Benchmark”
Wow! It’s amazing if someone knows how! 
Thanx a lot!
