Backtesting tab gone missing

Dear community, 

I downloaded the latest version of cTrader at the ed of May. The next day I opened the software the backtesting tab was missing. I can only do backtesting now when I go to public settings in a timeframe of 1 month, 6 months and 1 year. I am no longer have this backtesting tab. Is there a plugin or something I can install to have this easy sliding backtesting version (attached)?

Thanks!

Kind regards,

Saskia
