Fortiwifi devices do not have an option for 5.0ghz

Hello, 

I recently downloaded FortiPlanner lite v2.3.1 to try it out. 

When setting up a floor plan, the locked settings for the Fortiwifi 60D/C etc. are all set to 2.4ghz only. 

my current firewall - a Fortiwifi-POE-60D is running on 5.0 currently. 

Is this a setting I can change in the software, or is this a limitation I can work around somehow?
